Detailed Product Description

Proving Tanks are precision made, open volumetric calibrating measures.  They enable on-site calibration of liquid Flow Meters, Master Meters and Vehicle Tanks with a high degree of accuracy and reliability.

Design Features

- Rugged and fully welded construction.

- Displacement tube for accurate volumetric adjustment.

- Internal baffle plate prevents vortex formation and related trapping of air.

- Provision to mount thermometers and level bottle for accurate liquid measurement.

- Fixed or mobile versions with or without unloading pump and motor.

Applications

- Calibration of field mounted liquid Flow Meters or Master Meters.

- Vehicle Tank Calibration.

- Calibration of Bulk Measures.
