Product • Installation Diagram

Many installation matters need attention ｜2017 Overall Upgrade ｜ HUAHAI Instrument will display for you

Straight pipe section length of the turbine flowmeter is sensitive to flow velocity distribution distortion and rotational flow in the pipeline, into the sensor should be fully developed turbulent flow, Therefore, according to the spoiler type of upstream of the sensor, to equip the necessary straight pipe section or rectifier, to require the length of the inlet and outlet segments.

Type	Installation conditions	Type	Installation conditions
general condition		90°elbow
Two 90 ° elbows on the same plane		Two 90 ° elbows on different planes
Reducing pipe		Expanding pipe
Full open valve		Half open valve

If the situation of spoiler on the upstream side is not clear, the general recommended the length of upstream straight pipe section not less than 20D, the length of downstream straight pipe section not less than 5D，If the installation control can not meet the above requirements, the rectifier can be installed between the spoiler and the sensor. When the sensor is installed outdoors, there should be measures to avoid direct sunlight and rain-proof.
