Mechanical displacement meter provers

One of the main production lines of OGSB is Mechanical Displacement Meter Prover with capacity from 100 to 4000 m³/hour (ANSI 150 – ANSI 900).

Mechanical Displacent MeterProver is designed for calibration of different type flow transducers by multiple transferring of definite fluid volume. Mechanical Displacement Meter Prover is a complete technological unit that consists of a calibrated section, loading and receiving chambers, oil flow direction switching unit, piston detector switches, draining pipeline, washing and air removal systems connection devices, pressure and temperature measuring gauges.

The process unit is mounted on the metal base. The Company can provide heat insulation with stainless steel housing optionally.

The Company can also manufacture mobile type Mechanical Displacement Meter Prover mounted on special tilt-covered trailer. Manufactured according to Technical Specifications 26.51.52-002-95715144-2019. Pattern approval certificate of measuring instruments (Federal Agency on Technical Regulating and Metrology) № 60439/1.

Types of Mechanical Displacement Meter Prover implementation

Mechanical Displacement Meter Prover with Straight Calibrated Section

Measurement is performed with the passing of the sphere through the straight section of the Mechanical Displacement Meter Prover, as a result no additional resistance occurs that happens while the sphere passes through the curved section in common configurations of Mechanical Displacement Meter Prover.

Advantages:

Decrease of pressure drop at the Meter Prover;
Increase of stability of the flow rate;
Provision of higher characteristics of repeatability and total accuracy of the measurements;
Increase of service life of epoxy coating of the pipes;
Reduction of piston amortization;
Less complexity of the Meter Prover construction;
No need for re-calibration of the Meter Prover after delivery to site due to undismountable construction of the calibrated section.
