Piping Precautions

(1)Design piping so that the flowmeter detector pipe is always filled with the fluid being measured,

whether the fluid is flowing or not.

(2)The detector has no adjustable piping mechanism. Install an adjustable short pipe where needed.

(3) The required straight pipe length should comply with the requirements as follows.

(4)Be sure to grounding the flowmeter according to below figure.
