SLW Liquid Turbine Flow meter Calibration Report Sample

SLW Series liquid turbine flow Meter is a precision flow measuring instrument for measuring low viscosity media such as water, diesel, gasoline, etc，it is a kind of speed flow meter.
The turbine flow meter has simple structure, high measuring accuracy, long service life, simple operation and easy maintenance.

Features:

• The pressure loss is small.
• The liquid turbine flowmeter has high anti-electromagnetic interference and anti-vibration capability, and has a reliable performance and long working life.
• The liquid turbine flowmeter adopts advanced ultra-low-power single-chip microcomputer technology, which has strong functions, low power consumption and superior performance. 
• Intelligent flow display with nonlinear accuracy compensation. The accuracy of the correction formula is better than ±0.02%.
• The meter factor can be set online by the button on the display, and can be displayed on the LCD screen. 

Each turbine flow meter is calibrated before leaving China turbine flow meter manufacture, below is the sample of Calibration Report Sample for customer's reference.
