Installation of electromagnetic flowmeter on process pipeline

Cologne electromagnetic flowmeters are mainly used in chemical industry, papermaking, food, textile, metallurgy, environmental protection, water supply and drainage and other industries. When matched with computers, system control can be achieved. The electromagnetic flowmeter has no moving parts and no flow blocking parts, which will not cause pressure loss, nor will it cause wear, blockage and other problems. This instrument is a volume flow measuring instrument and is not affected by the temperature, viscosity, density and conductivity (within a certain range) of the medium being measured during the measurement process. It has no mechanical inertia, is responsive, can measure instantaneous pulsating flow, and has good linearity, so the measurement signal can be linearly converted directly into a standard signal output using a converter.

Installation of electromagnetic flowmeter on process pipelines:

1. It can be installed on straight pipelines, or on horizontal or inclined pipelines, but the center line of the two electrodes is required to be horizontal. .

2. Vacuum in the pipeline will damage the lining of the flow meter, so special attention is required.

3. If the measuring medium is a heavily polluted liquid, install the flowmeter body in the bypass pipeline to drain and clear the flow without interrupting the process operation.

4. When installing a PTFE-lined flow meter, the bolts connecting the flange should be tightened evenly, otherwise the PTFE lining will be easily crushed. It is recommended to use a torque wrench.

5. Ensure there is sufficient space near the pipe flange for flowmeter installation and maintenance.

6. The flow meter measuring blocked pipe must be filled with medium at any time and cannot work normally when the pipe is full or empty. When the medium is not full in the pipe, the method of raising the height of the outlet pipe at the rear end of the flow meter can be used to fill the pipe with medium to prevent the pipe from being full and gas from adhering to the electrode.
