Product Details

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.

Configuration

1. Clamp Meter Holder

Application:
Primarily used for securing the instruments being calibrated in liquid calibration devices. It accommodates the structural length and connection methods of different types of instruments, ensuring no media leakage during calibration.
Standard small and medium diameter instruments are driven by a pneumatic source; standard large diameter instruments are driven by a hydraulic source.
Functions and Features

Specifications/Diameter DN15-DN2000;
Drive Type Pneumatic, Hydraulic;
Structure Internal Push Type, External Push Type;
Features Flexible connection, easy installation, reliable performance.


2. Steady
 Flow Tank

Specifications/Model 0.3~50 m³
Material Carbon steel, stainless steel;
Features The tank body uses a combination of baffles, sieve plates, and sieve tubes to effectively eliminate turbulence
and bubbles within the medium.
Applications Primarily used in liquid flow standard devices to stabilize the flow state of  the medium.

3. Commutator
Application:
Mainly used in static mass and static volumetric flow rate standard devices to switch the direction of medium flow.
Small and medium diameter open commutators adopt a swing nozzle structure; small and medium diameter closed commutators adopt an  internal piston structure.

Functions and Features

Specifications/Diameter DN15–DN800
Actuator Type Pneumatic, Electric
Structure Open, Closed
Commutation Time Difference ≤15ms
Features Reliable performance, agile operation, and rapid response
