•  Wide flow range
•  High degree of accuracy
•  No moving parts

The DELTAFLOW Vortex from OVAL was developed for measuring gas flow in large size pipelines. This Vortex flow meter includes a probe equivalent to a 2-inch DELTA vortex meter which is inserted in the pipe to determine the actual flow rate by measuring a representative flow velocity of the process fluid passing it. A thermistor sensor is used for vortex detection.
 
Features of the DELTAFLOW Vortex flow meter include:
​ 

• A wide flow range at a high degree of accuracy
• Exceptionally small pressure loss to save energy
• Model with a gas-purge sensor allows measurement of dirty gases and high temperature service (up to 350°C)
• Replaceable sensor assembly eliminates the need to interrupt the process during inspection or maintenance
• Inherently insensitive to vibration in the surrounding environment
• No moving parts to wear out giving a long service life
• Suitable for dirty gas flow

DELTAFLOW Vortex Flowmeter Industrial Vortex Meter for Gas Measurement Vortex flow meters with a thermistor sensor for vortex street detection. Changes in thermistor temperature lead to changes in resistance value and a train of pulses proportional to the flow velocity. A gas purge version is available for metering gases containing dust and mist, or high or low temperature gases.
