Installation Instructions

Installation Tips

1. Verify the actual internal diameters and wall thickness of the pipe before installing the Insertion thermal mass flowmeter.
2. First of all, 25 holes are opened in the pipeline, and the base is welded at the opening hole, and then the rest of the thermal mass flowmeter is loaded into the special ball valve together, and the depth to be inserted is calculated according to the actual pipe diameter and wall thickness. This step can be inserted to approximate size and hand tighten the nut.
3. Turn the sensor connecting rod so that the marked arrow is in the same direction as the medium flow.
4. According to the data measured in the field, convert the corresponding scale on the sensor connection rod, and lock the nut.
5. If you are horizontally installed, the display of this instrument can be flexibly installed at 90°, 180°, 270° to meet your actual needs.
6. 
   Mounting base
   
   Do not weld in an explosive environment.
   The environment with special requirements for welding should be operated in accordance with the relevant requirements.
   The base is divided into two types according to the different installation methods: welding and clamping. When installing, the base should be located at the apex of the section direction of the pipeline, and the axis of the base through the hole is perpendicular to the axis of the pipeline. The effect diagram of the welded base has been installed (the welding position has been treated with rust prevention).
   
   Installing ball valves
   
   Secure the stainless steel valve to the base. Use a gasket on the crimped contact surface (nylon material is used when the medium temperature is below 100 ° C, copper material is used when the medium temperature is above 100 ° C).
   
   punching
   
   Before drilling holes, check the site environment carefully to ensure the safety of operations.
   Close the valve in time after drilling to avoid air leakage.
   In the case that online drilling is allowed, the opening tool of Sen Ling Instrument Co.Ltd. can be used to realize online installation without stopping production. See related instructions for the use of the tool. When stopping drilling, a variety of methods can be used to punch holes, to ensure that the axis of the hole and the base of the hole axis concentric. If the hole is opened by gas cutting, the drilling operation should be arranged before the base welding
