Questions and Answers for Purchasing Electromagnetic Flow Meters
Electromagnetic flow meters are our commonly used
water flow meters.
When we buy and select magnetic flow meter, we will always encounter some questions. Today, CIXIFM winny has summarized some of our common questions for your reference.
If you have many questions and want to consult, please feel free to consult winny: sales01@cxflowmeter.com
What is the principle of electromagnetism?
Principle of electromagnetic induction (
Electromagnetic flow meter is an inductive instrument manufactured according to Faraday's law of electromagnetic induction to measure the volume flow of conductive medium in a pipe.)
What is the 4-20mA output of the electromagnetic flowmeter?
Four-wire system (two-wire system can be customized, the stability is not good)
Will there be interference if the electromagnetic flowmeter is installed next to the generator?
Yes, there will be a lot of disruption
The standard is the national standard flange, which can be customized, American standard, Japanese standard, thread, etc.
Can the electromagnetic flow meter be tested if the tube is not full? what is the reason?
Unable to measure, dissatisfaction with the pipe needs to customize an electromagnetic underdrain flowmeter
What kinds of materials are electromagnetic flowmeters made of? What are they?
Shell material, meter material, electrode material.
How many parts does the structure of the electromagnetic flowmeter consist of?
Pipeline parts: lining, electrodes, casing. Meter, or split meter + cable:
What is the turndown ratio of the electromagnetic flowmeter?
1:10
What does turndown ratio mean?
Ratio of minimum flow to maximum flow
How many materials are there for magmeter electrodes?
316L, Hastelloy B, Hastelloy C, Hastelloy C, Titanium, Tantalum, Platinum, Tungsten Carbide
How many materials are there for the lining of the electromagnetic flowmeter?
Rubber, Fluoroplastic (PTFE, F46)
Can the electromagnetic flowmeter flange be made to American standard?
can be customized
How many kinds of electromagnetic flowmeter displays?
Three types: no display, split display, integrated display
Can a magnetic flow meter display gallons?
can be customized
Can electromagnetic flowmeters be used for hygienic connections?
Can
How to calibrate the empty pipe of the electromagnetic flowmeter?
If necessary, the medium must be passed first to ensure that the pipe is full, then close the valve in a static state, zero the meter, and then open the valve for normal operation!
Is there any instantaneous display on the liquid crystal display head of the electromagnetic flowmeter? Or is it just showing the total?
Both instantaneous and cumulative display
Does the electromagnetic flowmeter have an alarm output?
High and low voltage can be output, and there are two corresponding terminals; the flow can only be alarmed by outputting 4~20MA or pulse to other receiving control instruments!
What is the minimum diameter and maximum diameter of the electromagnetic flowmeter?
DN10~2000mm
What is the accuracy of pipeline electromagnetic flowmeter?
DN10~300 is 0.5 grade, DN300~700 is 1.0 grade, DN700~2000 is 1.5 grade
What is the accuracy of the insertion electromagnetic flowmeter?
Level 2.5
How many units are displayed?
The standard is L/h, m3/h
What are the materials related to the medium?
electrodes, lining
Can the electromagnetic flowmeter be connected to a computer?
Yes, electromagnetic output 4~20MA or pulse, or RS232 or RS485 or HART protocol, as long as the PLC can receive such signals!
