- Before installing a flow meter, the user should check the packing list offered by the manufacturer, and do a preliminary inspection to confirm whether products were damaged by transport or other reasons.
- All flanges of the Flowmeters base on GB/T (China) standard. Other types of flanges can be offered according to other industry standards too.
- In order to ensure measurement accuracy, it is generally requested to set the length of forwarding and backward pipeline as figure 2. And in order to ensure the maintenance flow meter online, it should set the by-pass pipeline.
- Flowmeter is generally installed in a horizontal position.
- 1, 2, and 3 are respectively the front, behind and by-pass valves and 4 is the flow.
- meter. L≥10D and L>=5D are respectively front and behind pipelines whose lengths are larger than 10 and 5 times of the pipe diameter respectively.
- When installation in vertical position, medium flow direction is should from down to up.
- Do not allow installing valve or bend part between front and behind valves that may change fluid state and infect measure accuracy.
- Impacting on the flow meter during installation should be avoided that would damage the flow meters or bring zero offsets.
- Flowmeter should be coaxial with the front-behind pipeline, and this can reduce measurement error produced by the change of flow state.
- The arrow direction on the measuring tube should be consistent with the flow direction.
- When the flow meter is installed in the open-air, it should be taken certainly to avoid directly washing by rain.
- If 4~20mA, 0~10V, impulse, or RS485 outputs are set, 24VDC power is needed to be supplied.
