Adjustable
Paddle
- From half to full
diameter. Easily changed to accommodate flow/media
changes, half-full lines, fluid separation, etc.
- Extremely sensitive
unit designed for minimum actuation.
- Available in explosion
and non-explosion proof models in screwed of wafer tees. Recommended
for line sizes up to 2" inclusive.

- These
units -- designed for extreme sensitivity -- allow full
flow with minimal pressure drop. Flows of less than 0.01
GPM can be reliably detected.
- Low flows of gases require a special feature
to compensate for chatter created by the compressibility of
gas. This is accomplished by introducing a constantly
expanding taper on the inlet side, so when the paddle moves
the gas expands uniformly.
