Electromagnetic flowmeter hidden skills introduction

Electromagnetic Flowmeters (EMF) are new flow measuring instruments that developed rapidly with the development of electronic technology in the 1950s and 1960s. An electromagnetic flowmeter is an instrument that applies the principle of electromagnetic induction to measure the flow of a conductive fluid based on the electromotive force induced by the conductive fluid through the application of a magnetic field.

As an advanced meter for measuring liquid flow, people who are in constant contact are no strangers to the operation of the flowmeter. But, dare you say that you really understand the electromagnetic flowmeter?

Anyone who has played games knows that in addition to some common skills, game characters often hide hidden skills, which are called big tricks. Big moves are usually not used often, and they are only used when they are urgent.

In the same way, the electromagnetic flowmeter that we usually take for granted also hides the "big move" that most people don't understand. Below, it reveals the hidden mystery of the electromagnetic flowmeter and reveals its three hidden skills.

Skill 1, the negative accumulation function of electromagnetic flowmeter

Generally, we all know that there will be an arrow indicating the direction of flow on the body of the flow meter. When installing, we will install it in the direction indicated by the arrow, so that the measurement is correct.

However, the electromagnetic flowmeter has such a hidden skill, that is, the negative accumulation function, that is, when the flow flows in the opposite direction, the measurement can still be performed, but the negative value is displayed.

This hidden function can have unexpected effects in some special situations on our site.

For example, in some industrial applications, when liquid metering is performed, liquid reflux occurs frequently, and at this time, there is a negative cumulative flow. In particular, when the liquid is counting money, there is a negative cumulative flow, and the flow of the reverse flow can be counted in, and a net accumulated value is obtained to achieve accurate billing. The function of Party A must be super like.

Skill 2, the direction modification function of the electromagnetic flowmeter

This and the previous skills can be said to complement each other. Generally, when installing our flowmeter, we must ensure that the installation direction is correct, but there is also a situation that happens. At this time, this hidden skill can be started.

Because of the "two-way measurement" feature of the electromagnetic flowmeter, we can measure it like the normal direction by simply enabling the function of this direction modification. In addition, in some special industrial sites, it is often measured to flow to different media, which is a function that requires two-way measurement. This is the time when the electromagnetic flowmeter is showing its talents!

Skill three, pulse equivalent output function of electromagnetic flowmeter

This function is mainly used for factory coefficient calibration and user metering. The pulse equivalent corresponds to the cumulative amount, indicating that each pulse corresponds to a corresponding volume. Pulse equivalent (L/P) One pulse represents how much L flow

When the factory is factory calibrated, one of the calibration methods is the pulse equivalent output calibration. The flow meter is calibrated by converting the number of pulses output at intervals to the cumulative flow rate.

In addition, in some of our industrial sites, customers also need flowmeter output pulse signal to some display instruments or PLC, DCS, after receiving the corresponding number of pulses, they can be directly converted into cumulative flow, convenient and fast!

How do you feel that we are ignoring our electromagnetic flowmeters? We have learned about its three big moves, and we will be more convenient in the future.
