Introduction

QLCS liquid calibration device, utilizing both the standard meter method and the gravimetric method, consists of a circulating water pressure stabilization system, a variable frequency speed control system, a standard meter pipeline system, a tested meter pipeline system, a flow rate adjustment system, a switching system, a weighing system, and a computer control system. The device can be used for metrological verification and calibration of electromagnetic and liquid flow meters.

Advantages

1.    Combines static gravimetric & standard meter methods (shared water source/pipeline/control system) – simple,easy to operate, efficient, cost-effective.
2.     Rational range; multiple electronic scales ensure full-range weighing accuracy >0.05%.
3.     Flow adjusted via frequency converter + manual ball valves – stable, energy-saving.
4.     Pneumatic meter clamps, electric drain valves, diverters (synchronous timing/counting) – automatic weighing, computerized data processing, calibration report generation.
