2.Parts Descriptions
The TEM-1-K ultrasonic water meter has wired type as the standard configuration, wireless type need to be customized.
3.Installation Instructions
3.1 Choosing install position
When install the water meter,the upstream straight pipe line shgould be ≥5D, downstream straight pipe line should be ≥3D, 20D from the pump(D is the pipe diameter), and ensure water must be full of the pipe lines.
3.2 Installation Method
4 Calibration Method
The water meter is calibrated via constant-current method. &RQVWDQWFXUUHQWPHWKRGLVWRPDNHWKHFDOLEUDWLRQGHYLFH
VWDQGDUGZDWHUPHWHU DQGWHVWHG water meter into stable flow state at a set flow point, calibrate the water meter by measuring accumulative flow at the same time. Different calibration methods may cause errors. If use start-stop method to calibrate the water meter, it may cause errors. Try to extend calibrating time when you use start-stop method to calibrate water meter, and make sure the duration of each turn on time should be more than 60 seconds at least. The less time you calibrate, then bigger error you will get.
