5. Instructions for use

5.1. All transmitters are digitally calibrated, and different transmitters are completely consistent and interchangeable;

5.2. During transportation, all transmitter batteries are disconnected. When installing the pressure transmitter on site, you need to unscrew the back cover of the meter head and connect the battery. Pay attention to tighten the sheath to prevent water leakage;

5.3. To install the pressure transmitter on the pipeline, first close the valve (needle valve or gate valve) on the pipeline where the pressure transmitter is to be installed. Then there are two installation methods: (1) screw the transmitter directly into the upper port of the valve; (2) screw the union or adapter into the upper port of the valve, and then screw the transmitter into the upper port of the union or adapter. This installation method uses the addition of a union or adapter to adjust the direction. After the installation is completed, open the needle valve to confirm that there is no leakage, which means the installation is qualified;

5.4. If the temperature transmitter is not used for a long time, please open the back cover and disconnect the battery;

5.5. For detailed installation and debugging, please refer to the product operation manual.

6. Notes
