Electromagnetic flowmeter calibration equipment upgrade

Kaifeng Kamboda Industrial Instruments Co., Ltd.

National-Class Calibration System Upgrade

We are pleased to announce the full upgrade of our flow calibration equipment, further enhancing the precision and reliability of our electromagnetic flow meters.

Our newly commissioned standard volumetric flow calibration systems (Model LJX-14S & LJX-1S) have been officially inspected and certified by the National Institute of Metrology (NIM, China), achieving the high-precision 0.3 accuracy class.

Key Calibration Specifications

LJX-14S: DN50–DN300, flow range 0.16–1300 m³/h

LJX-1S: DN350–DN1000, flow range 6.25–2000 m³/h

Expanded uncertainty: U_rel = 0.30% (k=2)

Repeatability: ≤0.03%–0.04%

Fully traceable to NIM primary water flow standards

In full compliance with JJG 643-2024 and international metrology requirements
