CDi.P5.FTe Submersible Natural Gas Flowmeter

Obsolete (new ones can no longer be made), but still in use.

Poor man's long-term flowmeter just got a whole lot better in functionality, not to mention the facelift.

Direct descendant of the CDi99.P5 as tested at PM station in 2001, will produce graphs like this.

Uses a reinforced solenoid to switch between the two pressures across the camco box.

Eliminates temperature-related inaccuracy by reading both pressures with a single transmitter.

Saves power by keeping track of the last switch state, so only one switch action per reading.

Uses quick-connects so cylinder and/or transmitter changeout in the field is easy.

Works at the bottom of Lake Erie for years without recharge; Bulletproof... no filters, no manifolds, no check valves, no drip pods, will measure up to 120psi differential pressure.

Beats the big boys at their own game, at least 12 years, hands-on, in-the-field, development.

Optional second pressure transmitter, usually used to record casing pressure.
