Water Meter Test Method

 

(Based on ISO 4064 Class B standard)

 

Step 1: Assemble water meter and fix it by using special tool, then put the water meter into the test bench.

 

Step 2: Pressure test – The water pressure rises to 20 bars and lasts for 1 minute. If the water meter passes the test, it will pass to next step. If not, it will return to Step 1.

 

Step 3: Accuracy Test

1. Qmax (3,000 l/hour): Firstly, we record the initial reading of water meter, for example 00000.0000 m3. Then a total of 20 liters water will go through water meter, at the flow rate of 3,000 l/hour. Then we read the after-testing result of water meter, for example 00000.0200 m3. The after-testing result (00000.0200 m3) minus initial reading (00000.0000 m3) equals to 0.0200 m3 (20 liters). Thus the water meter is accurate and the tolerance is 0% (The allowable tolerance is +/- 2%). If the water meter passes the test, it will pass to next test. If not, it will return to Step 1.

 

1. Qn (1,500 l/hour): Firstly, we record the initial reading of water meter, for example 00000.0200 m3. Then a total of 20 liters water will go through water meter, at the flow rate of 1,500 l/hour. Then we read the after-testing result of water meter, for example 00000.0400 m3. The after-testing result (00000.0400 m3) minus initial reading (00000.0200 m3) equals to 0.0200 m3 (20 liters). Thus the water meter is accurate and the tolerance is 0% (The allowable tolerance is +/- 2%). If the water meter passes the test, it will pass to next test. If not, it will return to Step 1.

 

1. Qt (120 l/hour): Firstly, we record the initial reading of water meter, for example 00000.0400 m3. Then a total of 10 liters water will go through water meter, at the flow rate of 120 l/hour. Then we read the after-testing result of water meter, for example 00000.0500 m3. The after-testing result (00000.0500 m3) minus initial reading (00000.0400 m3) equals to 0.0100 m3 (10 liters). Thus the water meter is accurate and the tolerance is 0% (The allowable tolerance is +/- 2%). If the water meter passes the test, it will pass to next test. If not, it will return to Step 1.

 

1. Qmin (30 l/hour): Firstly, we record the initial reading of water meter, for example 00000.0500 m3. Then a total of 10 liters water will go through water meter, at the flow rate of 30 l/hour. Then we read the after-testing result of water meter, for example 00000.0600 m3. The after-testing result (00000.0600 m3) minus initial reading (00000.0500 m3) equals to 0.0100 m3 (10 liters). Thus the water meter is accurate and the tolerance is 0% (The allowable tolerance is +/- 5%). If the water meter passes the test, it will pass to next test. If not, it will return to Step 1.

Note: All the test benches used for calibration of water meter are inspected and adjusted for accuracy by the government institution twice per year.

Step 4: If the water meter passes all the tests above, it will be sealed and packed.
