6.The water meter is calibrated using the constant current method:
When our products are produced, all flow meters are calibrated one-on-one.
The constant flow method is to make a calibration device (standard water meter) and make the water meter under test enter a stable flow state at a set flow point. Calibrate the water meter through the following methods:
At the same time, the cumulative flow rate is measured. Different calibration methods may cause errors. If the start-stop method is used to calibrate equipment, errors may occur. Use the method of prolonging the calibration time when starting and stopping to calibrate the instrument, and ensure that the duration of each start time should be at least more than 60 seconds. The less time it takes to calibrate, the greater the error will be.
7. RFQ:
1. Q: What is the difference between industrial ultrasonic water meters and household water meters?
