Tinsleys Flow Meter Calibrators are portable, easy-to-use kits for verification of the accuracy of differential pressure instruments, recorders, controllers, transmitters and indicators. The differential pressure design incorporated enables calibration of flowmeters.

The units feature a diaphragm actuated digital test gauge which indicates the pressure in various engineering units. The system includes a squeeze bulb, rubber tubing, and quick-disconnect fittings.

Pressure bulb has a high volume with integral checks and bleed valves.
