Ultrasonic Heat meter (BTU meter / Calorie meter) for cooling and heating energy measuring meter, Based on OIML-R75 and EN1434 standards, it has a memory to save data and errors for 12 months.


By using the above measured values and sending the consumption data to the server, it will be possible to separate the engine room costs, including the separation of the gas bill and the separation of the electricity bill of Chillers.

The main components:

DN15 UP TO DN40 Ultrasonic water meter

Choose size and model:

Each meter has a minimum flow rate (Q2), nominal flow rate (Q3) and maximum flow rate (Q4).

First, the circulation flow rate of the cycle should be calculated and after referring to the technical table, it should be compared with the flow rate of different sizes. The best option is to match the cycle flow rate with the nominal flow rate (Q3) of the meters.

Ultrasonic meters size 1/2 inch (DN15) to 11/2 inch (DN40) are produced from brass type with threaded connections, the copper joint are a part of the meter and must be used during installation.

Heat meters must be installed at the inlet of the cycle unless it is not possible to install the meter at the outlet of the cycle.
