5 Types of Liquid Flow Meter that Measure Liquid Pressure

A flow meter is an equipment used to measure the amount of liquid flowing through a pipe. Liquids are in terms of volumetric flow rate and mass flow rate. Liquid flow rates are crucial to various industries. Most industries available power, oil, water, and waste treatment. It drives them to use a liquid flow meter to determine the amount of production. It not only quantifies the liquid but detects leakages, which lead to wastage.

There are different types of flow meters for measuring liquid

Differential pressure Flowmeter

It is the most common type of flow meter device in use. Statistics state that over 50 percent of all liquid flow rate applications use this type. It comprises primary and secondary components. The primary ingredients are the kinetic energy, which uses a nozzle, venturi tube, and flow tube. On the other end, the secondary part rates the differential pressure and triggers a signal. This signal can be modified to get the flow rate. Most Various types of flow meters are standard in the oil and gas industry. This unit should match the pipe size, flow conditions, and the liquid’s properties.

Mass flow Meters

It measures the quantity of fluid flowing through a particular point per unit of time. This flow meter comprises Coriolis and Thermal Flow Meter. These flow meters are the most efficient as they measure the force produced by the speed. Mining and water waste use mass flow meters.

Channel Flow Meters

It refers to the water flowing on the surface; it examines the flow rate by measuring water depth. It has two types, Weirs and flumes. According to the structure’s shape and size, these dam-like structures allow for a limited free flow of liquids.

Velocity flowmeters

Meters weigh the velocity of flows, which are, in turn, the volumetric flow rates. The speed of the flows is then calculated back to the volume of the flows. Reynolds numbers are used to determine the velocity of the liquid flows. Vortex flows mainly consist of vortex shedding, paddle wheel, and the ultrasonic flow meters.

Positive Displacement Flow Meters

Positive Displacement types of Flow Meters, weigh the volume filled with liquid, transport it further, and fill it. There is a rating of the quantity of liquid transfer. The liquid flows are different from other types. Their positive flow meter weighs the actual liquid flow.


A liquid flow meter weighs the mass and the volumetric flow of liquids. The distinction contains functional and technical aspects. Values, and the nature of liquid measured on them. They are essential to a broad range of industrial sectors. It lays its basis on its areas of application.
