ULTRASONIC COLD WATER METER
ULTRASONIC WATER METER
Ultrasonic Water meter for sanitary water measuring meter, Based on OIML-R45 standard, it has a memory to save data and errors for 12 months.
Usages:
These meters are produced in two models, cold and hot water sanitary , which are generally used to separate the water bill and gas bill of the building units according to the consumption of each unit:
a) Measurement of hot and cold sanitary water consumption of different parts (Zone) of the building to separate the water bill of the building units
b) Measuring the thermal energy consumption of sanitary hot water in different parts (Zone) of the building to be used in the separation of the gas bill of the building units
c) Measurement of flowrate for monitoring in the industry sector
The main components:
- Meter body and copper joint
- 2 Ultrasonic sensors
- 1 temperature sensors for install at the body of meter
- Electronic board and Battery
Network:

In building units where the sanitary hot water return pipe is installed inside the unit, one measuring meter should be installed on the inlet pipe to the unit and one on the outlet pipe of the unit to compare the amount of incoming and outgoing water and measure. Its difference obtained the amount of sanitary hot water consumed.
It is necessary to explain that, due to technical reasons, the measurement of this amount requires special knowledge and technology, which is exclusively at the disposal of behsaz Energy Company.
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.
