Static pressure test of ultrasonic water meter

Views: 14     Author: Site Editor     Publish Time: 2019-07-09      Origin: Site

According to the regulations, the ultrasonic water meter needs to be subjected to a static pressure test. The purpose of the static pressure test is to test that the ultrasonic water meter can withstand the specified test water pressure according to the maximum allowable working pressure level of the ultrasonic water meter, without leakage or damage.

I. Ultrasonic water meter static pressure test preparation In the ultrasonic water meter static pressure test, we need to prepare the following test: 1. One or a batch of ultrasonic water meter is installed on the test device. 2. Exit the pipe of the test device and the air inside the ultrasonic water meter. 3. The test device is leak-free. 4. Guarantee supply pressure without pressure fluctuations.


Second, ultrasonic water meter static pressure test procedure Ultrasonic water meter static pressure test process is more complicated, we need to pay attention to the following procedures in the test: 1, increase to 1.6 times the maximum allowable working pressure of the ultrasonic water meter and keep 15min. 2. Check the ultrasonic water meter for mechanical damage, external leakage and water in the indicator device. 3. The pressure is increased to 2 times the maximum allowable working pressure of the ultrasonic water meter and kept for 1 min. The flow should be zero during the test. 4. Check the ultrasonic water meter for mechanical damage, external leakage and water in the indicator device. 5. The pressure should be gradually increased and decreased during the test to avoid pressure fluctuations. 6. The sonic water meter static pressure test is only carried out at the reference temperature.
