Flowmeter installation and dimensions

2. Simple installation method of flow meter

●To meet the requirements of the straight pipe flowmeter installation point open a Φ 100 round.

●Use Φ109 x 4.5mm base section and open good mouth round the welding line, base after welding visual inspection may not have obvious askew.

●Insert the velocity probe into the pipe, adjust the insertion depth so that the center of the probe and the central axis of the pipe want to be consistent, the Angle between the center line of the probe and the central axis of the pipe should not be more than 5 degrees, and then adjust the flow direction mark to make it the same as the flow direction of the fluid.

●Connect flange or ball valve to welded base and bolt.

3.Ball valve type flowmeter (with globe valve) installation and removal method

Technical requirements

●Non-injection size and materials are determined by the user according to the pressure strength and anti-corrosion requirements.

●The "mounting base" shall be in a correct position on the pipe without obvious deviation.

●Non-steel pipes may be clamped to fix the "mounting base" provided that the gap size shown in the drawing is 85mm so that the bolt M16 × 65 is bolted from the gap when installing the ball valve.

●Standard for flange connection dimensions: GB4216.4-84
