Split-type electromagnetic flowmeter selection

Date:2019-12-23 source:

Split-type electromagnetic flowmeter selection, split-type electromagnetic flowmeter motor selection high pixel backlit LCD display information, all Chinese characters order simple practical operation, easy to use, easy to use, under the strong light can clearly read at night.

Split-type electromagnetic flowmeter selection

Has the two-way total flow, the two-way total output total function, the electric flow, the frequency has the two-way output function.

The instrument panel system software can be used to measure the total flow of strong alkali and strong acid rather than waste water and concrete slurry, etc.

Converter output functions: not only 4-20ma, monopulse output, but also RS485 or RS232, HART and other digital communication and GPRS wireless network information remote transmission.

Scope determination

Generally, the velocity of the measured material in the industrial electromagnetic flowmeter should be 2 ~ 4m/s. Under unique conditions, the very low velocity should not be less than 0.2m/s, and the very high velocity should not exceed 8m/s.If there are solid particles in the material, the common flow rate should be less than 3m/s to avoid excessive friction between the lining and the electrical level.For viscous fluid mechanics, the flow rate can be selected to exceed 2m/s, a large flow rate is conducive to the automatic removal of adhesion on the electrical level of the effect, conducive to improve the precision of measurement.

Under the standard that the measuring range Q has been defined, the size of the steam flowmeter specification D can be determined according to the category of flow rate V above, and the value can be calculated by the above formula:

Q = PI D2V / 4

Q: total flow rate (㎡/h) D: nominal pipe diameter V: flow rate (m/h)

The range Q of the electromagnetic flowmeter shall exceed the estimated very large total flow value, while the normal total flow value shall slightly exceed 50% of the full range scale of the steam flowmeter.

Porcelain city Shanghai instruments co., LTD., is the world's leading instrument manufacturers, technology has always been the cornerstone of our company to survive, but we always use direct marketing, cancel the agent, so we can keep in close contact with customers, more important is to ensure that after-sales, delivery, price, etc., really do to ensure that the interests of the customer.
