Installation requirements for electromagnetic flowmeters
Electromagnetic flowmeter installation requirements, some time ago many friends told me the electromagnetic flowmeter installation problem, think this is a lot of people do not know the problem.What are the installation requirements of the electromagnetic flowmeter?What are the key points to pay attention to when installing electromagnetic flowmeters?Today porcelain xi network here to everyone say, hope to help everyone to eliminate the heart of the problem!
Installation requirements for electromagnetic flowmeters
1. Selection of natural environment for sensor installation:
(1) installation in areas with high ambient temperature should be avoided as far as possible.The integrated electromagnetic flowmeter also depends on the ambient temperature of the electronic components, which is lower.
(2) the sensor should be installed in the area of dryness and natural ventilation, to prevent damp and cold, very easy to store water and flood site, but also to minimize the sun and rain immediately.
(3) there should be no strong leakage current in the pipelines where sensors are installed, and machinery and equipment with strong electromagnetic field should be avoided as far as possible, such as major mechanical and electrical engineering, major transformer electrical appliances, etc., to prevent the influence of electromagnetic field;
(4) the pipeline or road surface where the sensor is installed does not need to have obvious vibration, so it is very much a one-piece instrument panel;
(5) the location of the sensor installation shall take into account the indoor space for on-site maintenance by the operator.
Ii. Selection of natural environment for converter installation
(1) ambient temperature between -10 ¡æ and 45¡æ;
(2) air humidity of gas ≤85%;
(3) the installation address has no obvious vibration;
(4) surrounding gas is free of corrosive vapors;
(5) the converter should be installed in the room as far as possible.Installation in the outdoor, should also be used to prevent wind and sun countermeasures
Electromagnetic flowmeter installation should pay attention to which
The installation of the sewage pipeline at the mouth of the mouth shall be installed at the lower part of the pipeline;If the pipe undulations exceed 5m, install the automatic exhaust valve in the middle and downstream of the sensor;
Electromagnetic flowmeter should be installed in the middle and downstream of the sensor pressure regulating valve and emergency cut-off valve, but not installed in the upstream and downstream of the sensor;
The sensor must not be installed in the pump import and export trade, should be installed in the pump inlet and outlet;A method of installing an electromagnetic flowmeter in a precise measuring tank;
The electromagnetic flowmeter should be installed in the lower part of the horizontal pipe and the vertical upward part to prevent installation in the highest and vertical downward part of the pipe;
The electromagnetic flowmeter shall be installed at the pipe elevation;
Porcelain city flowmeter after hundreds of working medium, the service life of more than 8 years, and without secondary calibration, since it was founded, the porcelain city instrument is determined to do the world first-rate flowmeter, breaking the monopoly of the industry, international brand in the flowmeter to customers in the domestic can buy real German quality domestic flow meter.
