clamp meter/low cost intelligent turbine flowmeter /high quality liquid turbine flowmeter

When the nominal diameter is 2mm and the flow rate range is 0.040~0.13m3/h, the

intrinsic error is: ±1% of reading, and when the flow rate is ≤0.040m3/h, the intrinsic error

is ±1% of full scale value.

When the nominal diameter is 3mm and the flow rate is 0.085~0.250m3/h, the intrinsic

error

is: ±1% of reading, and when the flow rate is ≤0.085m3/h, the intrinsic error is ±1% full

scale value

The flow rate ranges indicated in the table are regular values, if needed, they may be

properly expanded as user’s requirements. The minimum flow rate may be extended to

about 0.3m/s, ,it may be still lower for some specifications, and accuracy in the extended

area will be indicated as the relative error of the full range value.

Measured medium: liquid (avoiding multiphase flow)

Viscosity range of medium:≤5mP·S

Calibration: calibrated with water before leaving the factory
