Hi, this is little control in the butler, is on a Friday, I wish you all a happy holiday in advance, today we brought a small, very easy to learn knowledge, what are the power supply of electromagnetic flowmeter, understanding also convenient after we better use of electromagnetic flowmeter, and see it together,

Electromagnetic flowmeter is a chemical enterprise substance determination of a flow meter, if liquid has the conductivity of the corresponding, to select electromagnetic flowmeter in flow measurement, the characteristics of high quality flowmeter calibration work, electromagnetic flow meter in the water, waste water, sulfuric acid, ammonia and other conductive liquid application more, electromagnetic flowmeter is different from the volumetric flowmeter, electromagnetic flowmeter work depends on the supply of electricity, for different working conditions, the flow distribution way at present there are three key, respectively is 220 v ac mains power distribution, 22 v dc power distribution, battery power (the key is the high performance lithium) distribution,

There are several kinds of electromagnetic flowmeter supply
A, 220 v power distribution, electromagnetic flowmeter applied at present stage, industry has a 220 v power supply on the spot, usually if flowmeter in accordance with the regulations to carry out the installation, no need in addition to other device, can work on electricity, the 220 v power distribution can also be made from fission type electromagnetic flowmeter can be made into an organic whole,
Two, 22 v power electromagnetic flowmeter is suitable for the industrial spot do not allow the application of an alternating current or consider to choose bottom pressure from the security level of dc field, or by integrating instrument with flow totalizer.especially for electromagnetic flowmeter in power distribution, can choose only 22 v battery power distribution, electromagnetic flowmeter applied at present stage is not too much, the key for some on the spot without any power under the conditions of use, moreover also has the common fault alarm function, flow is set up and down and alarm function, positive and negative phase flow to carry out the switching function, with 485 communications, electromagnetic flowmeter in addition to have different ways to power distribution, its intrinsic function is also very strong, can be used to determine the velocity of liquid substances and to determine the flow of material and reverse flow, can determine the instantaneous flow and cumulative flow, can be made into one and two separate, according to the regulation of the customer to decide,
Three, the battery power is in the condition of no external power supply on the spot, or for security reasons on the spot is made under the condition of battery power, can show the instantaneous flow rate on the spot, the cumulative flow, can dispense to connect power cost, in the environment of the more remote the battery power distribution way is particularly important, the key weakness is that to regularly carry out inspections and battery replacement,

Will be here, today's small knowledge is very simple, have you learned? Follow the housekeeper learning every day, welcome attention ah,
