DELTAFLOW Vortex Flow Meter
Downloads
- 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.
