Venturi Flowmeters utilize differential pressure in order to measure the rate of flow of a substance within a system. Venturi flowmeters are highly popular in many industries and in commercial processes.

Orifice Plate Flow Meters, are devices that are used to measure the rate of flow within a system. This type of flow meter provides data of the volumetric or mass flow rates of a fluid depending on the reading that is taken from the orifice plate. Orifice plate flow meters utilize the same principles as venturi flow meters as it uses the relationship between the velocity of a liquid and the pressure of the liquid to determine what the velocity of the flow of liquid actually is.

Thermal Mass Flowmeters come in two types namely in-line type and insertion type flowmeter includes the flow sensing element, temperature sensing element and the probe assembly that supports the sensing elements. The insertion style flowmeter probe assembly may be inserted in to any suitable flow section, pipe or duct.
