Brief Introduction

Electromagnetic FlowmeterIntroduction: Electromagnetic flowmeter is20century60A new type of flow measurement instrument that has rapidly developed with the advancement of electronic technology. Electromagnetic flow meters are made according to Faraday's law of magnetic induction and are used to measure the volumetric flow rate of conductive liquids. Due to its unique advantages, it has been widely used in the measurement of various conductive liquids in industry. For example, measuring various corrosive liquids such as acids, bases, salts, etc; Various flammable and explosive media; Various industrial wastewater, pulp, sediment, etc

Application of electromagnetic flowmeterPulp flow measurement, juice flow measurement, dirty process fluid measurement,Micro flow measurement, cold water flow measurement. Measurement of oily wastewater, Hot water flow measurement, household heat measurement,Building heat measurement, water meter measurement, Pump efficiency testing, process flow measurement, open channel flow measurement. Softened water flow measurement, large diameter sewage measurement, power plant cooling water measurement, non full pipe flow measurement, corrosive flow measurement, untreated sewage measurement, tap water flow measurement, high-pressure natural gas measurement, factory discharge liquid measurement, non-contact flow measurement. Measurement of water pump outlet flow rate

5Protection level of electromagnetic flowmeter. According to the national standardGB4208-1984Same as the International Electrotechnical CommissionIECstandard(IEC529-7B)The standard for the protection level of the shell is:IP65For the anti spray type, it allows the faucet to spray water from any direction onto the instrument, with a spray pressure of30KpaThe water output is0.75m3/hThe distance between the water nozzle and the instrument is3m；IP67To prevent immersion, the instrument can be completely submerged in water, and the point should be at least underwater150cm, with a duration of at least30min.IP68It is a submersible type that can work underwater for a long time. According to the above regulations, instruments that are prone to flooding should be selected for underground installationIP68Electromagnetic flow meters are suitable for installation on the groundIP65.
6Select grounding based on the insulation of the connecting instrument pipeline.
7Select the nominal pressure of the electromagnetic flowmeter based on the pressure of the measured medium. For the medium pressure, it is10MPaThe16MPaThe25MPaThe32MPaHigh pressure electromagnetic flow meters should be selected for flow measurement of several levels. Its caliber is100mm.
Electromagnetic FlowmeterInstallation requirements:
The liquid should have the required conductivity for measurement, and the conductivity distribution should be generally uniform. Therefore, the installation of flow sensors should avoid areas that are prone to uneven conductivity, such as adding liquid near the upstream and setting the liquid addition point downstream of the sensor.
The sensor measuring tube must be filled with liquid during use(Non full pipe exception)When mixed, its distribution should be roughly uniform. The liquid should have the same potential as the ground and must be grounded. When insulating materials such as plastic are used in process pipelines, friction and static electricity may occur during the transportation of liquids, resulting in a potential difference between the liquid and the ground.
