Installation

Note for installation

1.Environment for installation should be dry and wind, avoid shining from sun, temperature of environment is not more than 40.

2.It should be far away from high magnetic place o electric equipment. Such as large transformer, welding machines.

3.It is should be far away from the place including NH3, acid fog.

4.The direction of fluid flow is similar with flow mark.

5.Pipe is installation should be filled with measuring medium. it cannot be empty.

6.The instrument should not be installed inside pipe with negative pressure avoiding lining shedding.
