Ultrasonic heat meter

Ultrasonic Heating and Cooling Meter (Heat Meter/BTU Meter) is built with ultrasonic measurement technology and complies with OIML-R75 and EN1434 standards. It features a memory for storing consumption data for up to 12 months and logging potential errors.

Applications of the Ultrasonic Heat Meter

Measuring heating and cooling energy consumption in individual units of a building equipped with fan coils, radiators, underfloor heating systems, etc.
Measuring heating and cooling energy consumption in air handling units (AHUs), unit heaters, and similar equipment.
Measuring heating and cooling energy consumption in various heat exchangers, such as swimming pool and jacuzzi heat exchangers.

By using the measured data and transmitting the consumption to a central server, it is possible to:

Segregate Boiler Room Costs: Allocate gas bills.
Segregate Chiller Costs: Allocate electricity bills for the building’s shared cooling systems.

Size and Model Selection

Each heat meter has a minimum flow rate (Q min), nominal flow rate (Q nom), and maximum flow rate (Q max).
First, the cycle’s circulating flow rate must be calculated. Then, refer to the technical table and compare it with the flow rates of different sizes. The best selection is to match the cycle’s flow rate with the nominal flow rate (Q nom) of the meter.

Ultrasonic meters ranging from 1/2 inch to 1 1/2 inches are made of brass with threaded connections. The union adapter fittings are part of the meter and must be used during installation.

The preferred installation location for energy meters is at the cycle’s inlet unless installing the meter at the inlet is not feasible.
