    Water & BTU Meters

    Water and thermal energy (BTU) metering is essential for HVAC cost allocation, chilled water plant optimization, and district energy billing. Emergent Metering offers the EES series of ultrasonic water and BTU meters in both clamp-on and inline configurations — covering pipe sizes from 1" to 48" without cutting into the pipe or interrupting water service.

    Clamp-on ultrasonic meters mount on the outside of the pipe using transit-time measurement, making them ideal for retrofit applications where system shutdowns are not an option. Inline meters provide the highest accuracy for new construction and critical measurement points. BTU meters pair flow measurement with supply and return temperature sensors to calculate thermal energy transfer in chilled water, hot water, and condenser water loops.

    All EES meters support Modbus RTU and pulse output for integration with data acquisition servers, building automation systems, and energy dashboards. For district energy and campus applications, multiple meters can be aggregated through an AcquiSuite A8812 or Tridium JACE controller for centralized monitoring and billing.
