Q:What is the role of the earth ring of the electromagnetic flowmeter?
In general, if the pipe is made of metal material, it can also be not suitable for the ground ring. It will connect the flange and the pipe of the flowmeter and then connect it to the ground. It can also be used well, especially in the case of large caliber. If the small bore, with the ground ring does not matter, the cost will not be much worse. In addition, some users do not test the strong corrosive media, but the pipe is non-metallic, then it is necessary to match the ground ring, grounding is very important for electromagnetic. The magnetic field interference is fatal for electromagnetic, because we can take some measures for electric field shielding, but we have no way of magnetic field shielding, electromagnetic flowmeter installed so we must avoid the strong magnetic field.
Q:Why is the grounding of the electromagnetic flowmeter important? How to ground?
Because its potential signal is small signal, encounter interference, immediately wash out the normal signal. The grounding can avoid the potential produced by the erosion of the fluid in the pipeline, and at the same time, the zero of the measuring potential is the same as the zero of the medium, and the vortex flowmeter avoids the error of the poor students.It is equipped with a grounding ring, and then connect the earth ring to the pipe. If it is lined with a third electrode to ground.
Q:What are the flow meters applicable to?
Such as thermal power plants, chemical plants, pharmaceutical factories, laboratories, hotels, restaurants, and geothermal power plants
Q:The difference between pitotbar flow meter and Del Taba flowmeter
Fluid conditions are differentBy measuring pitotbar flow meter is suitable for any pipeline fluid fluid; single phase flow, bidirectional flow can be measured; low requirements for straight pipe; in effect measuring medium on impurities, easy to block.* Del the medium must be filled with fluid pipeline; must be single-phase flow, two-way flow (such as gas mixture flow) cannot be measured.
Q:What does "flow meter" with temperature and pressure compensation mean? When should I use warm pressure compensation?
Significance of temperature and pressure compensationTemperature and pressure compensation usually refers to the measuring data is at the temperature of 25 degrees, the pressure for a standard atmospheric conditions for the measurement of temperature and pressure usually and standards are different, so the general instrument can measure the temperature and pressure field, and then through the calculation formula for automatic compensation of measurement results. For example, air flow measurement, such as the general flow meter orifice flowmeter, dual D, Pakistan Annubar flowmeter etc. are the current volume flow temperature and pressure, but when the volume of air quality by temperature pressure influences the calculation formula is: PV=NRT=>m=MPV/ RT state equation of ideal gas, which is about R constant. 8.314J/ (mol K); P Pa; M gas pressure, the molar mass of the substance is (or mixed gas average molar mass); V m3; T gas volume, system temperature, unit K. In order to approximate the calculation, the temperature is considered as 20 degrees C (293K) at normal temperature, and the gas is approximately ideal gas.
Q:How many methods are used to measure gas flow? How is it measured?
Compressed air is taken from the atmosphere, and the atmosphere contains a certain amount of water vapor. A large bore orifice flowmeter used to measure the flow of compressed air. There are always accumulated water in front of the orifice, which affects the measurement accuracy. There is usually a section of water in the draft pipe, which makes the differential pressure measured by the differential pressure transmitter not consistent with the differential pressure produced by the throttling device. These are common causes of air borne water errors.
Q:Before the pump, how far can the flowmeter be installed?
Look, what kind of flowmeter do you have?. If it's volumetric type. It is not recommended to be installed in front of the pump. The main reason is that:1) the inlet section of the pump will form negative pressure, which will lead to cavitation;2) the volumetric efficiency of the pump varies with the inlet and outlet pressure differential, and the front flow meter readings do not agree with the actual outflow;
Q:Can the electromagnetic flow meter measure the flow rate of softened water?
You really need to use electromagnetism, you can only use a capacitive electromagnetic flowmeter. Currently on the market the main parameters used is the conductivity of a medium must ensure that, if only to soft water calcium and magnesium ions conductivity or enough, you may get some medium with pointer multimeter measuring a resistance value, the conductivity is not enough to see.If the conductivity is not enough, see the installation environment conditions, the caliber of the requirements, choose other flowmeter. Of course, the work characteristics of the medium should be taken into consideration.
Q:What aspects should be paid attention to in the selection of mass flow meters?
The volume of a fluid is a function of fluid temperature and pressure, is a dependent variable, and the mass of a fluid is a quantity that does not vary with time, space, temperature, and pressure.
Q:What are the power consumption of some flowmeters?
The operating current of the fixed ultrasonic flowmeter is 50mA
