Laminar V series

Laminar V series

Laminar V series

V Series volumetric flow transmitters are calibrated for air as standard but available for use on many types of gas. By measuring the differential pressure produced by flow through a laminar flow element, an inherently linear reading is converted using modern electronics to give a voltage output, and an integral liquid crystal display. With a ten-millisecond response time, these units out-perform most thermal type meters.

 

More details:

The V series Volumetric Gas Flowmetersare designed for applications venting to atmosphere, with constant back pressure or with little to no back pressure. They do not include absolute pressure or discrete temperature sensors, which makes them an affordable alternative to mass flowmeters. As with the M Series, the Volumetric flow meters use discrete Differential Pressure sensor measurements within the laminar flow region to determine flow.

Other gas calibrations available, including: argon, carbon dioxide, carbon monoxide, ethane, helium, hydrogen, methane, nitric oxide, nitrogen, nitrous oxide, oxygen and propane.

Calibration to 0.5% of full scale, other output types and units with 13 gas switch select are available. Please consult Sales.

Blind units are available, please consult Sales for prices.
