    Tips: Digital Gas Flow Detector Installation

    The gas flow meter is preferably installed horizontally. Flow direction should be the same as the direction of the arrow mark on the meter body. If there may be particles or debris in the fluid, a filter is strongly recommended to be installed upstream of the meter.

    Please follow the below steps to complete the installation:

    1. Check if the meter is complete, no visual damage first.

    2. Before installation, make sure that there is no debris or particles in the pipe.

    3. During installation, it is recommended to first install the inlet of the flow meter and then the outlet. To ensure the accuracy of measurement, the straight pipe length should be remained enough at the installation site of flow meter, upstream no less than 10 times DN and downstream no less than 5 times DN.

    4. Make sure all the wire connections of the flow meter is correct including the wires for LCD, input/output and communication.

    5. Turn on the power supply, and ensure that the LCD works properly.

    6. Slowly turn on the valve of the pipeline, and then the flow meter starts to measure the gas flow in the pipeline.
