There are numerous sorts of stream meters accessible for use in modern computerization. Contingent upon the item to be estimated, regardless of whether it be fluid or gas, some essential standards apply to how the meters work.
How about we take a เครื่องวัดflow meter. The deliberate fluid must be water-based or conductive. This settles on the mag meter an incredible decision for squander water or procedure water that is viewed as fouled or messy.
Mag meters are volumetric meters that have no moving parts. This is perfect for those regions where you wouldn’t have any desire to be presented to the deliberate fluid while dealing with the meter.
The manner in which a mag meter works depends on a recipe called Faraday’s equation. Initially, once more, the fluid must be conductive. A voltage is estimated that is subject to the normal speed of fluid occasions the quality of the attractive field times the length of the conductor (this is the separation between the cathodes).
This is all that great science stuff, you know like E = m × c 2. It’s Einstein’s hypothesis of relativity. We’ve all known about or seen the condition. Huge numbers of us don’t have the foggiest idea what it implies be that as it may, the individuals that do realize how to utilize the condition have utilized it to for both advantage and burden, eg: the nuclear bomb.
We don’t have to realize Faraday’s equation to utilize a mag meter. We don’t really even need to comprehend what that recipe is, we simply realize that whoever created the mag meter utilized the equation to deliver a sign voltage that can be estimated by your mechanization procedure.
While mag meters work dependent on Faraday’s equation, other stream meters work in various ways. For example, a mechanical stream meter makes them move, inward parts which may not fit with explicit applications, for example, grimy water that conveys enormous particles that may cause harm or block the inner parts.
The mechanical stream meter has a rotational gadget inside, for example, an oar wheel or a propeller. Fluid coursing through a channel causes the revolution of the inward oar, which makes a stream rate that is corresponding to the rotational speed of the interior oar.
The mechanical stream meter is simpler for laymen to comprehend. Hawking a bike gradually moves you gradually, while accelerating rapidly will move you a lot quicker. Direct connection between’s the means by which quick the pedals turn (in this manner haggles) quick you go not far off. No equation required, simply pedal quicker, move quicker.
Same guideline as the inner oar, the quicker it is pivoting, the more stream experiencing the channel which thusly, sends a graduated sign to your PLC.
