PanPower Electric Meters - Hardware and Security FAQ

Which OS is used for the Bridge
Where are the Panoramic Power Wireless Sensors installed?

PAN-10 and PAN-12 sensors must be installed on an un-shielded electric wire at the electric panel level. PAN-14 and PAN-42 sensors require external current transformers (CTs) for their current input and those are also installed at the electric panel level on an unshielded cable. All sensors are designed for AC powered devices only. 

What is the measurement accuracy of the PAN-10/PAN-12 sensors?

The typical measurement accuracy for the PAN-10/PAN-12 sensors is 2%. For PAN-10, it is designed for currents ranging between 3A and 63A and for PAN12, it is for currents ranging between 10A and 225A. Accuracy is not defined beyond these ranges. For more information please refer to the sensor datasheet.

What is the measurement accuracy of the PAN-14 sensor?

PAN-14 uses a standard 5A-output current transformer (CT) to measure current. The primary current range is determined by the CT rating. The typical accuracy for PAN-14 is 2%, at the current range of 0.1A to 5A at the CT’s output (2%-100% of the full current range). For example, if a 100A:5A CT is used, the PAN-14 sensor’s accuracy is defined as 2% for a primary current of 2A to 100A.

Do the sensors measure true RMS current?

Yes, the sensors measure true RMS current. The measurement is accurate even if the current waveform is distorted.

How do you guarantee the accuracy of the sensor?

Each sensor is calibrated in the factory prior to shipment using high-accuracy equipment, to meet the specified accuracy levels. The calibration parameters are stored in the cloud and are used by PowerRadarTM to display the readings. When working with the bridge via Modbus TCP, the calibration parameters are stored inside the bridge.

Do I need to calibrate my sensors periodically?

No. There is no need to re-calibrate the sensors.

How are power and energy calculated from the sensors’ data?

Power is estimated by PowerRadar using fixed voltage (based on Panel's Connection Type configured) and power factor values provided by the user during sensor deployment. Power is then aggregated over time to obtain the consumed energy value.

Can I certify the sensors for sub metering accuracy?

The current sensors do not provide sub metering accuracy because they only measure current (and not voltage or power factor).

Can I use the sensors for sub metering applications?

In environments where power factor and voltage are stable, the overall accuracy of energy (kWh) measurements over time is expected to vary between 2% - 8%. Many of our customers choose to use our current sensors in such cases, due to the ease of installation and low-cost vs standard sub metering.

Can I use the PAN-42 for sub metering applications?

PAN-42 is a true power meter, and provides current, voltage, power and energy (kWh) measurement accuracy of 1%.

Is PAN-42 a utility/revenue-grade meter?
PAN-42 was tested by a 3rd party lab for 1% accuracy according to ANSI C12.1 class 1. This accuracy is sufficient for many billing-level applications, such as M&V, sub metering, etc.
Despite its tested accuracy, PAN-42 is not officially certified as utility grade. This is due to some utility meter requirements (such as an outdoor enclosure and an LCD screen) which it does not have.
Do PAN-10/PAN-12/PAN-14 sensors assume power factor of 1 to get kW?

All current sensors (PAN-10/PAN-12/PAN-14) uses the PF as defined on the circuit the sensor is installed on through the Deployment Tool. The default value is 0.95.

Is it possible to add in 'virtual data sets' on PowerRadar? For example, if we monitor 1 main and 1 sub-main, can we have the option to add in another sub-main which will then be a subtraction of the sub-main (monitored directly) from the main (also monitored directly)?

This set up is supported using our Device Groups functionality, currently only available in Time View.

If we have a PAN-42 meter installed that shows us the power factor, can we automatically use that measured power factor for subsequent downstream sensors?

Short answer is no. PF is not the same identical across the site or panel hence to get the accurate PF, a PAN-42 must be installed on the specific device. 

How critical is the actual direction of current once you install PAN-10/PAN-12? There is a small arrow on the sensor for the direction. If sensor installed not according to the direction of current, what happens?

It has no effect at this time. The only sensor installation that is direction sensitive is for the PAN-42 sensor. 

For devices with multiple cables for one phase, what if the loads on the cable are unbalanced?

This is a rare use case, in most instances the cables of the same phase should be balance.
If you still suspect they are not, best option is to use one large current transformer to capture all cables with a single sensor.

What is the purpose of the 9 pin D-connector on the PAN-42?

The connector is used during the manufacturing process of the PAN-42. It is not intended for end users.

What are the sensitivity differences between PAN-10 and PAN-12? We've had installations where due to the cable size, we cant install two PAN-10s but need to install one PAN-10 and one PAN-12. We get different current readings.

See full sensors specs in here. The main cause for inaccuracy with any of the sensors is the current level, 2% accuracy is only applicable for levels at 5% and above of the sensor rating (PAN-12: 225A | PAN-10: 63A)

Any plans to make the PAN-42 available on Modbus?

PAN-42 currently is not part of our Modbus TCP solution. We are reviewing the business case for it, and will be considered going forward.

Are any of the sensors Certified for ISO in a ISO 50001:2018 application


How do PAN-10 and PAN-12 sensors behave on VFD driven systems? Are the sensors installed before VFD on the feed cables from the panel?

On VFD-driven systems, they must be installed on the 50/60Hz side of the VFD, not the variable-frequency side.

Normally VFD emits some electromagnetic noise back to the panel/grid. How PAN10/12 read the current data if EM noise is present.

We have never seen an installation in which EM noise affects the current readings. If there is noise at the frequency of transmission of the sensors (434MHz/915MHz), this could cause reception issues between the sensors and the bridge – this will usually be seen as a high noise floor reported by the bridge.

What is the difference between Managed Load and Real-Time Consumption on the Site Dashboard?

Real Time Consumption is the site total at the moment you open the Site Dashboard, whereas the Managed Load shows the peak site power consumption for the last 2 weeks.

How can I receive Push Notifications from Alerts?

Push Notifications can only be sent to PowerRadar Users that have downloaded the PowerRadar app on the Mobile Device/Tablet and have logged into it at least once.

What are the voltage limitations of the PAN-42 sensors?


Do the PAN-10/PAN-12/PAN-14 sensors have any voltage limitations?

No. The only limitation is in the current since that is what they are measuring. Please refer to the Specification Sheets for the Sensor Family in the Hardware and Security Guides and Datasheets section.

What languages can I view PowerRadar?

Dutch, English, German, Italian, Japanese, and Spanish. These can be set under the Personal Preferences section under the white silhouette icon in the upper right corner of PowerRadar.

What does RSSI stand for?

Radio Signal Strength Index. It’s used to determine how strong the communication is between the sensors and the Bridge.

What is an acceptable RSSI range for sensors?

-30 dBm thru -75 dBm. If more than -30 dBm, move the Bridge further away from the sensor. If less than -75dBm, move the Bridge closer to the sensor.

How do I swap sensors on a device?

Click on uninstall sensor on the device and enter the new sensor's serial number and install. The historical data will stay on that device so long as the device isn't deleted.

How do I see uninstalled sensor(s) data?

On Energy Time View, depending on the Group By category selected (Device Type, Zone > Panel, etc.) navigate to that uninstalled device(s) category and right click on the header and select "Show Uninstalled Devices" to view its historical data. 

Why are there region specific hardware? For example, why can’t I install an EU sensor in the US and vice versa?

Different regions around the world have different frequencies utilized by the grid. To accommodate this, Panoramic Power has hard coded the power frequency into the sensors and therefore offers different versions of the same sensor (US, EU, Japan East, and Japan West). Using a sensor designed for one region in a different region results in wrong measurements and much higher wake up current.

Are there data retention policies applied to the energy data on PowerRadar?

Yes. For 1 minute interval data, it is available on PowerRadar for the most recent 3 months. After 3 months, the smallest resolution available to view historical data on PowerRadar is 5 minutes for up to a year. After a year, the smallest resolution available for historical data is 15 minutes. There are no data retention policies for 15 minute, 1 hour, 1 day, and 1 month interval data. If 1 minute interval data is paramount for your company, you can directly export the data within the first 3 months of its posting or set up an automatic Export Job.

Is there a way to find the EMEI number of a Cellular Bridge?
Yes. Put the Bridge into Configuration Mode and open the Configuration Tool ( In The Network Setup tab, the "Connection type" should be "Cellular".
Now go to the Diagnostics tab, choose at the bottom "Cellular" radio button, enter  "AT+CGSN" and press enter and the IMEI number will appear in the Diagnostics screen.
What is needed for an upgrade for a Bridge?

You will need the 3 firmware files (available upon request by submitting a support ticket) to be put on a blank USB flash drive of 8GB or less in memory size, the Bridge, its power supply, an ethernet cable, and a computer/laptop. 

What monthly data plan do you recommend for the SIM Cards used for cellular operating Bridges?

It depends on how many sensors are within the Bridge's range and how often the sensors are operating (nonstop vs. only during operating hours). In the case where a Bridge has 25 sensors that are operating all day and all night, the recommended data plan would be 500MB per SIM Card. 

What does it mean if the Bridge's power LED is solid orange?

This means the Bridge is checking the remote upgrade channel. This action does not disrupt the performance of the Bridge nor its connectivity to PowerRadar. A solid orange or solid green power LED is an operational state for the Bridge and is not a cause for concern.

Can I move a site from one account to a different account?
No. You can move an account (with ALL of its sites) from one VAR to another VAR, but individual sites cannot be moved. 

If a site's sensors need to be associated to a different account, you will need to uninstall the sensors, create a new site in its new account, and redeploy/reconfigure the sensors under the new site. 

If the historical data is important to preserve, there are two options. One way is to manually export the data to a .CSV file from Energy Time View prior to the uninstallation/site deletion. Second option is to uninstall the sensors but NOT delete the devices. Leaving the devices intact with no sensors will maintain all historical data.

Emergent Energy Ultrasonic Transit Time Meters - FAQs

What pipe sizes can the meters be used with?

The meters can be configured to work with a range of pipe sizes. Currently, our strap on ultrasonic flow meters will support measurement of pipes that range between 1" - 48" pipes. If there are any specific applications that falls outside of this range, please reach out to for further support. 

What pipe material will the meters work with?

Our ultrasonic flow meters work on a variety of pipe materials, as long as they are not jacketed or has excessive corrosion that might hinder transmittal of ultrasonic signal through the pipe. For this reason, PVC piping and copper piping are idealistic installations. Carbon steel and rigid pipe offers some complexity as there might be excessive corrosion inside the pipe. For installation onto painted surfaces, the installer should sand off (smooth) the painted surface. 

What fluids will the meters work with?

The meters will work on water based applications, which included water and glycol blends that are within the meter's rated operating range. 

How do I know what the proper spacing needs to be to install the meters?

Once the outside diameter of the pipe is entered into the meter, the meter will provide the actual installation spacing of the sensors to ensure a good quality signal. 

What are the power requirements for the meters?

The meters are configured for 24VDC power, but the supply power can range between 10VDC to 36VDC. If the customer's specific application has specific needs, we can also provide power converters for these specific applications. We can also provide pre-built panels that includes power supplies and the necessary integration components for our metering solutions. 

Open Protocol and Integration

The meters can communicate through a multitude of options. It can provide a scaled 4-20 mAmp signal as well as scaled pulsed outputs through the built in relay. There are also MODBUS RS-485 communication options. 

Panel enclosures for meters?

Our panels are standard ABS low voltage enclosures that includes a cord whip and pre-mounted and wired components. Please discuss with us your specific needs and we can build a panel that will house our meter and meet your integration requirements.
