FLOMID FX series is an advanced magnetic flow meter that is suitable for measuring conductive liquids with great accuracy and repeatability. Because of no moving parts or obstruction in the meter body the flow meter offers very low pressure drop and high durability. It comes in compact (integral) as well as remote (separated) mounted versions.

Vortex meters are known to be superior devices for steam flow measurement due to their inherent linear measurement, large turndown, low-pressure drop, and high accuracy. When sizing a vortex meter, it is common to have to reduce the line size using concentric reducers to increase the velocity through the meter for optimum performance.

Vortex Meters can be used for a wide range of fluids, i.e. liquids, gases and steam. They are to be seen as first choice, subject to verification to cover the requirements of a particular application. Vortex meters are essentially frequency meters, since they measure the frequency of vortices generated by a "bluff body" or"shedder bar".

However, unlike other SLVA flowmeters, the TVA does not rely on the measurement of differential pressure drop across the flowmeter to calculate flow, measuring instead the force caused by the deflection of the cone via a series of extremely high quality strain gauges. The higher the flow of steam the greater the force.

Vortex meters are actual volume flow meters, like orifice meters. These being intrusive meters like orifice meters, will cause the pressure drop as flow is increased, resulting in a permanent loss. consequently, liquids near their boiling point, could introduce cavitation as the pressure across the meter drops below the vapor pressure of the
