Instantly measure three process parameters, including mass flow rate, temperature and pressure from a single device. This one-stop solution saves you valuable time getting the data you need about your gas flow.

The local display can be set to scroll through the variables, as shown in the picture to the right, or to be set on one primary variable. If the totalizer is turned on, it will also be part of the scrolling loop.

Pressure Port

An optional pressure sensor port makes the meter fully multivariable. Temperature and mass flow velocity are standard with every meter.
