Vortex shedding flow meters are versatile and rugged meters that can be used in high-pressure gas, water, and steam applications.
Our vortex shedding flow meters will help you achieve your flow measurement goals.
Key Features:
Unlike many competing flow meters, vortex shedding flow meters measure gas, water, and steam flow without moving parts like rotors. This design makes vortex shedding flow meters less prone to mechanical issues and much easier to maintain.
When a mass flow measurement is desired, the VortiFox vortex shedding flow meters offer three measurements in one device: velocity, pressure, and temperature. VortiFox vortex shedding flow meters give flexibility with more process variables in fewer process connections.
Most flow meters require recalibration at annual intervals to avoid sensor drift. The VortiFox Models VF3 Insertion and VF4 Inline do not require periodic recalibration to maintain accuracy. This feature keeps Fox Thermal's promise to make downtime a thing of the past.
Vortex flow meters measure fluid velocity using a principle of operation referred to as the von Kármán effect. It states that when flow passes by an obstruction in the flow path, vortices are generated in a repeating pattern.
In a Vortex flow meter, this obstruction is often referred to as a bluff body. The bluff body causes the process fluid to separate and form areas of alternating differential pressure known as vortices around the backside of the bluff body. In VortiFox vortex flowmeters, a sensitive piezoelectric crystal sensor detects these vortices. The frequency at which the vortices are shed is directly proportional to the flow velocity. With the fluid velocity and area of the pipe known, a volumetric flow rate is calculated.
With optional integrated temperature and pressure sensors, VortiFox vortex flowmeters can provide a compensated mass flow rate. With the energy monitoring option, VortiFox meters can also provide a reliable (BTU) energy measurement of water, thermal oils, and steam.
Insertion style vortex flowmeters are a more economical option on large line sizes and can be installed under full process conditions by hot tap.
The VortiFox Model VF3 multivarialbe transmitter offers reliable vortex shedding flow measurement with fewer process connections. It is CE, FM, and FMc approved, along with ATEX and IECEx. Applications include wet steam, saturated steam, and superheated steam.
