The PTX2980-FD Compressed Air Flow Meter features a thermal mass design, gauging the flow rate of compressed air and nitrogen via the heat required to maintain the differential between its probes. The PTX2980-FD is built to operate accurately up to 200psig, with a clamp-design that projects two probes within the selected piping through 3/16in drilled holes, streamlining the installation process (no welding required).

Weather resistant materials and inbuilt surge protection mean low maintenance and reduced labor. In addition to an easy to read LED display, the PTX2980-FD offers streamlined navigation. The user is able to utilize a single button on the front of the meter to alternate between rate, daily usage and cumulative usage, as well as select a default display option, change units of measurement, and reset totals. The PTX2980-FD has an optional eight banks of memory for continuous logging of flow history, with a one million+ sample capacity per bank. Optional RS-485 output for networking is also available.

The PTX2980-FD comes with a wall-plug DC supply for 110 to 230V AC main with a 6ft cable plus a 14ft extension cable. Alternatively the user can hardwire the meter to a 24VDC supply. The PTX2980-FD features an inbuilt milliamp output, and is shipped with a jumper to power it directly from the flow meter's DC power supply.
