MOBILE CALIBRATION UNIT Russian patent published in 2019 - IPC G01F19/00 G01F25/00 

FIELD: measuring equipment.

SUBSTANCE: invention can be used for verification of fluid volume or volume measuring devices in operating conditions. Proposed test bench comprises standard measuring unit installed on support frame structure, strain gauges and electric pump. Support-frame structure is fixed on automobile trailer, which is equipped with wind-proof casing. Support-frame structure is made with possibility to bring standard measuring device into horizontal transportation position and includes transport platform installed on frame, two vertical guides of hydraulic mechanism of synchronous lifting and lowering of measuring device and lifting plates with central through holes for arrangement of rotary elements and auxiliary container of spill reception. Standard measuring element is fixed through upper and lower reinforcement rings in metal frame made in the form of three-ray lower base with angles between axes of beams equal to 120°, and triangular upper base, connected in pairs by three welded posts. Strain gauges are arranged under the beams of the lower base of the measuring device frame and are installed on the frame through metal plates.

EFFECT: safe transportation of the calibration device and improvement of calibration accuracy of fluid mass or volume measuring devices.
