Here is an easy to install insertion meter with turbine meter accuracy. The low mass non-metallic turbine rotates in direct proportion to fluid velocity and can provide local flow rate and total information with no external power required. 4-20 mA signal outputs are also available for control and automation functions.

The 22 Series probe has its own integral screw jack mechanism for "hot tap" insertion through a 1.5 inch full port ball valve at pressures up to 400 psig. By rotating the crank handle at the top of the probe, the turbine is lowered through the open ball valve into the stream. What an improvement over the "tighten down nuts on three threaded rods in rotation" method!

This instrument is ideal for periodic sampling or permanent installation. It is often used as a flow prover for other metering devices in large line sizes.
