6. Installation
1.) Installation ways
3 .) The choice of installation location
2.) The choice of installation environment
2.) Flowmeter curve graph of the relationship between Diameter, flow rate and flow
Electromagnetic flow sensor if not installed properly, will significantly affect measurement accuracy,
even lead instrument not working properly, so Before installation instructions carefully read the
relevant sections.
Sensor installation method for the flange connection. Criteria and process pipe welding flange screw
holes in the inter-position, bolt can be passed smoothly to facilitate the integration between the sensor
and process piping.
Installation must ensure that sensors Center and the process pipe center line, and then a good
grounding line, otherwise it would cause measurement error.
According to the work of instrument characteristics and technical characteristics, the choice of
instrument installation environment should pay attention to:
(1) The instrument should be installed at the ventilation to dry, avoid installing at the place easy
accumulation water.
(2) The instrument should try to avoid just sun shine and rain. Open-air installation, should keep out
rain in places;
(3) Installation of places as much as possible to avoid strong vibration;
(4) as far as possible to avoid a strong electromagnetic field equipment; such as large motors, large
transformers.
(5) Select the ease of maintenance, activities, convenient place.
Installed on the sensor in the pipeline, we should note the following points
(1) sign the direction of the flow sensors and pipeline flows in the same direction within the medium;
(2) The need to ensure that sensor tube is full filled with the measured medium;
(3) The sensors should be five times the upstream straight pipe section D above, the sensor should
be three times the downstream straight pipe section D above (available from the center of sensor ,
D to measure the pipe diameter);
