What is flow measurement?
Flow measurement can be called the quantification of a fluid's movement. Flow measurement is one of the oldest works of instrumentation. Flow measurement is vital in the industrial field. Even in rocket science, features of flow are needed. All its various applications expand its measurements in your everyday processes such as water service, gas stations etc.
What are flow measurement devices?
The flow measurement device is used in a varied range of applications for measuring fluid's movement through the system. You can find different kinds of fluid flow measurement monitors and tools for accommodating different types of fluids. Flow measurement instruments usually include flow switches and flow meters that offer precise repeatable outputs. You can measure and regulate with ease, no matter whatever liquid or gas is required to measure.
We can have a look at different flow measurement devices:
a) Liquid Meters
This device has a unique ability for measuring the low flow rates of liquid. It can measure from a few gallons/ minute to even low like 1 gallon/ year (10cc per day). The low flow meters effectively measure very low- but high-viscosity liquids that include magnesium sulphate, liquid chlorine, sodium hypochlorite etc. You can configure every flowmeter from a diversity of chemically compatible alloys like Monel, titanium and stainless steel. These are durable flowmeters and can be used in high pressure, high temperature and explosive operating conditions.
b) Gas meters
The gas meters are perfect to measure gas flows irrespective of the characteristic of gas (it may be dirty, explosive, corrosive). Gas meters can work with almost every gas like butane, ammonia, methane and sulfur dioxide.
c) Duct flowmeters
These ideal ducts from 1 inch to several feet in their diameter are best for air gas flow measurement. These flow meters offer reliable flow measurement, It is used for monitoring digester gas, stack gas and vent air. The flow measurement instruments can be easily installed and are designed to offer low maintenance services to users. It can be also used with non-condensing gases, even corrosive and explosive ones. Its design mainly eliminates the possibility of errors.
d)Flow Controller
Flow controllers are capable of measuring and controlling immensely low flow rates but with great accuracy. These are usually used with most of the homogenous liquids and gases with high/low viscosity.
e) multi-sensor flowmeters
These are unique flow meters that usually incorporate 4 measurements
1) Flow
2) Pressure
3)Temperature
4)Humidity
The probe present in this flow meter separates water air components and the transmitter offers vital output to the control system. The multi-sensor flowmeters are ideal to install at power plants condensers, evaporation monitoring, industrial drying and vacuum pump capacity monitoring.
So all the above-mentioned instruments for flow measurement are best to measure the quantity and flow rate of gases, liquids, air etc. The flowmeter instruments do not have any moving parts and can be easily installed on your system. Range setting can be optimised according to your needs and flow measurements instruments remain unaffected by deposits as well as contaminations.
