Dimensions


Note: This vortex flowmeter has 3 types of pillars a, b, c, with different sizes. You can check the height of the entire meter corresponding to the H superscript in the table above.
For the height of vortex flow meter with 150℃ sensor without compensation, see H superscript “c”; for the vortex flow meter with 150℃ sensor with compensation, see H superscript “b”; for the vortex flow meter with 260℃ sensor, see H superscript “b”; for the vortex flow meter with 300℃ sensor, see H superscript “a”.
Low cost vortex meter can measure the flow rate of liquids, gases and steam, applicable pipe size from DN15 to DN300. High accuracy vortex flowmeter has fully isolated design, optional LCD display for direct data reading, selectable various signal output like pulse output, 4-20mA output and RS485 communication, as well as integrated pressure / temperature compensation for precise compressor air or steam measurement. With clamp or flange connection and power by Li-ion battery, the vortex meter is easy to install, low-maintenance, reliable and safe.
