3D model of Standart Calibration Rig with the main elements description
Standard rigs based on gauging tank and flowmeter are used for primary and periodic calibration of Mechanical displacement meter provers with 100 to 4000 m3/hr capacity. These rigs evaluate the volume of calibrated section and perform calibration of Mechanical displacement meter provers. The principle of action employs the flowmeter working as a comparing unit to transfer the first class gauging tank volume to the Mechanical displacement meter prover that is being calibrated.
Standard calibration rigs consist of:
All components are structurally connected with piping and placed on the metal platform. Standard Calibration Rigs are connected to Mechanical displacement meter provers via flexible hoses.
Standard Calibration Rigs are fabricated according to the requirements of TU-4213-003-95715144-2009.
Standard Calibration Rigs have Pattern Approval Certificate of Measuring Instruments as well as included in the National Register of Measuring Equipments.
The advantages of such types of Standard Calibration Rig are:
Standard Calibration Rigs perform the following functions:
Standard Calibration Rigs can be stationary, mobile and explosion proof. Has GOST Russia Certificate of Conformity (for operation in explosion hazard zones) № 0030176.
