Explaining Working Of A Magnetic Flow Meters

A magnetic flow meter (mag flow meter) is a volumetric flow meter which does not have any moving parts and is perfect for wastewater applications or any grimy fluid which is conductive or water based. Magnetic flow meters will for the most part not work with hydrocarbons, distilled water and some non-aqueous plans).

Magnetic Flow Meters screen the influent, which touches base at the site’s three huge force mains from various areas over the county.

Things being what they are the conductivity of the liquid doesn’t go into that calibration constant. Here’s one approach to consider it. Suppose, for straightforwardness, that the flow velocity is uniform. At that point we should take a gander at the entire circumstance from the reference frame very still as for the liquid. In that reference frame that has a pure magnetic field in the lab becomes to some extent an electric field. In nice cgs units, the electric field E in that frame is E=(v/c)B, where B is the lab magnetic field, to lowest order in v/c. So that implies that in these units, with c= speed of light, :

V= (v/c)BL.

Here V is in statvolts, B is in Gauss, and L is in centimetres.

Conversion to SI units or others isn’t hard.

V (in volts)= v(in meters/second) * B (in tesla) * L (in meters).

In a genuine instrument, the liquid speed isn’t constant all through the tube, being biggest in the middle, so the successful “L” may be somewhat not quite the same as the basic geometrical distance, if for “v” you utilize the normal velocity.

In the event that you utilize this voltage to drive an external circuit that implies that some current is flowing at right edges to the magnetic field and to the liquid flow. The magnetic field applies a force on that present, in the bearing restricting the liquid flow. So whatever work is finished by the current needs to originate from work done by whatever is pushing the liquid flow, generally as you suspected.

Rotameter Flow Meters- Measuring the Rate of Flow of the Fluid

Measuring the rate of the flow of fluids is very important. For this purpose flow meters are used in fluid systems of liquid and gases. The flow meters can also control the rate of flow of a fluid if they are equipped with a flow control valve.

Rotameter flow meters are a particular kind of flowmeter, based on the variable area principle. They provide a simple, precise and economical means of indicating flow rates in fluid systems. This variable area principle consists of three basic elements: A uniformly tapered flow tube, a float, and a measurement scale. A control valve may be added if flow control is also desired. In operation, the rotameter is positioned vertically in the fluid system with the smallest diameter end of the tapered flow tube at the bottom. This is the fluid inlet. The float, typically spherical, is located inside the flow tube, and is engineered so that its diameter is nearly identical to the flow tube’s inlet diameter.

When fluid — gas or liquid — is introduced into the tube, the float is lifted from its initial position at the inlet, allowing the fluid to pass between it and the tube wall. As the float rises, more and more fluid flows by the float because the tapered tube’s diameter is increasing. Ultimately, a point is reached where the flow area is large enough to allow the entire volume of the fluid to flow past the float. This flow area is called the annular passage. The float is now stationary at that level within the tube, as its weight is being supported by the fluid forces which caused it to rise. This position corresponds to a point on the tube’s measurement scale and provides an indication of the fluid’s flow rate. The rotameter is a very popular device for flow measurement.

However, it must be made sure that these machines are always availed by the industry’s most reputed and renowned formulators. The suppliers must ensure that only reliable formulators are in their network, from which they procure their materials.

The Invention And Working Principle Of Rotameter Flow Meters

Flow meters, the perfect and ideal instrument for measuring the flow of the fluids is one of the most widely used industrial machine. Rotameters, also known by the name of variable area flow meters are used for measuring not only the flow rate of the fluids, but also of the gas present in the tube. The first of its time, variable flow meter, equipped with the feature of rotating float was invented by a person names, Karl Kueppers in Aachen in the year 1908. In the German patent 215225, it has been described. The brand name, Rotameter was registered by the British company, that is, GEC Rotameter Co in Crawley.

Going with the name, rotatmeter was called rotameter because they usually function by rotating in the glass tube. The basic function of Rotameter Flow Meters is based on the variable area theory. As per variable flow theory, the flow raises the float in the tapered tube that increases the passage area of the liquid flow. The float is expected and designed to reach a stable and steady position the moment the force or pressure applied by the flowing liquid and the buoyancy is equivalent to the gravitational force.

A drift or alter in the flow rate hampers the flow balance and the float moves up and down till it again reaches a state where the force is in equilibrium. The pressure fall across the float is extremely low and it remains generally steady as the flow rate alters. The meters are also intrinsically and essentially self cleaning in view of the fact that the flow of liquid or gas amid the tube wall and the float offers a scouring action which daunts the upsurge of foreign material. So, it was all about the working of rotameter flow meter which is regarded as the most useful industrial material.

Gas Flow Meter: Utmost Useful Industrial Machinery

Flow Switches: The Reason Why Are They Used?

A flow switch is a device which monitors the flow of liquid, steam or air. It sends a trip signal to a different machine in the system, like a pump. The flow switch point towards the pump for shutting off or turning on. Some of the all-purpose uses are for alarms, for cooling-circuit protection, pump protection, and for too low or too high flow rates.

Liquid flow switches could be used for hot water space heating systems, air conditioning, pump systems, blending or additive systems, water cooled equipment, fire sprinkler systems, liquid transfer systems, water treatment systems, industrial laser coolant systems and swimming pool chlorination. Air flow switches could be used for duct type heating, clean room filter systems, exhaust ventilating, air treatment system and air supply systems.

Flow Definition

Flow means the physical movement or velocity of liquid, steam or gas in a pipe which causes a switch to activate. No flow means a decrease in velocity or, at times, completes stoppage, letting the switch to slip back to its original position.

Function

A flow switch could perform specific functions as per the requirement. For instance, it could stop a motor while no flow is present; starting a motor while a flow is present, sounding an alarm while the flow stops or shutting off an alarm while the flow is apt.

Considerations

For fluid flow, computing the flow rate is inferred by computing the fluid’s speed or the change in kinetic energy. Velocity depends on the pressure disparity which is forcing the fluid through a conduit or pipe. Since the pipe’s cross-sectional area is recognized and remains steady, the average speed is a sign of the flow rate.” The flow rate requires to be decided to set the flow switch to the pre-decided close function.
