Product Description

The HFVT is a Vortex flowmeter for basic utility applications in all industries. The 2-wire device is the ideal choice when it comes to reliable flow measurement of conductive and non-conductive liquids, (wet) gases or steam where high accuracy is not required. The flowmeter features the robust Vortex technology of the HFVT product series, . This makes it one of the most cost-effective Vortex flowmeters in the market. This Vortex flowmeter is also equipped with the field-proven Advanced Vortex Frequency Detection (AVFD) technology for signal filtering, allowing stable measurements even under demanding process conditions.

Application

Steam applications: Determination of volume or mass flow under stable operating conditions

Gas applications: Determination of volumetric or nominal flow rates under stable operating conditions for gas, wet gas and gas mixtures

Liquid applications: Determination of volumetric flow rates of conductive and non-conductive liquids
