Where Liquid Flow Meters Are Used And For Which Applications

March 11, 2015 sarah Uncategorized

A variety of ultrasonic flowmeter and other liquid flow meters are available today. Usually, these types of meters can be used as the detection of your fluids quantity or flow. Among these kind of meters, you’ll find four common types. Kinds of liquid flow meters are:

Differential Pressure Meters

Differential pressure meters are also referred to as head meters. The way they have the liquid’s flow rate is from the measurement from the pressure differential besides the extraction with the square root. These kinds of flow rates metering systems are estimated at being used for just 50% of the time within certain sectors.

Like many other types of flow meters, differential pressure meters have both a primary and secondary element. The differential pressure that may be created within the pipe is due to the change in kinetic energy in the chief constituent. For this to work the liquid flow meter have to be equipped for your liquid’s properties and flow conditions.

Additionally, it must match the pipe’s size and possess ample accuracy over a certain amount of range. When it comes to secondary element, it is in charge of measuring and providing a read out or signal for conversion into a genuine flow value for the differential pressure.

Positive Displacement Flow Meters

The way that these liquid flow meters work is by accurately separating liquids in accordance with measured increments, then by proceeding to transfer them on. A connected register accounts for counting all the segments. Because of the way that each of the segments are representative of your discrete volume, these are popular within accounting applications and automatic batching. Usually, a confident displacement meter successful within the measurement of viscous liquids or when times require a simple mechanically comprised metered system.

Velocity Meters

These types of meters have a greater amount of range because of their lack of a square root relationship. Instead, they work lineally according for the volume flow rate. Generally, there is a low volume of sensitivity responding to adjustments to viscosity when they are used above Reynolds values of 10,000. Often, almost all of the velocity based meters have fittings or flanges so that they are prepared for fitting directly inside pipelines.

Mass Flow Meters

Mass flow meters are the effect of the continuing developments in response to the advantages of more accurate mass flow measurement system within mass related processes. A variety of types are available however the commonest form of liquid flow meter could be the Coriolis meter. Such a meter operates off of the Coriolis force.

Steps to Selecting the Right Flow Meter

Due to high amounts of flow meters inside industry that searchers complain usually do not perform in accordance with expectations, you should choose the right one. Actually, most of the problems encountered relates to the improper selection. It is therefore critical that somebody that is knowledgeable picks the flow meter. Methods the steps that the person should take when choosing a liquid flow measurement instrument.

1. Understand and consider how the flow meter will probably be used

a. Is high repeatability or accuracy more vital?

2. Do you want any sort of signal and is there any certain requirements?

3. What properties does the liquid contain?

a. Could it be slurry, viscous, or clean?

b. Does it conduct electrical current?

c. What’s its density or gravity?

Overall, there are a number of items to consider when choosing a liquid flow meter. Generally, the performance of the meter directly pertains to perhaps the right type was chosen. Therefore, the type of flow meter selected should go based on the technical information and specifications of the supplier.
