Zero Calibration
Zero Calibration provides the reference point for the flowmeter. It is necessary to conduct the zero calibration
whenever the Coriolis Meter is installed.
For Zero Calibration, follow the following procedure after installation:
• Warm-up the flowmeter for 30 minutes.
• Once the warm-up is complete, continue the flow through the flowmeter until the temperature of the
flowmeter is same as the working temperature of the fluid.
• When the flowmeter has reached the required temperature, close the downstream valve, and make the
fluid pass through the flowmeter under normal temperature, density and, pressure. Then close the
upstream valve to ensure the sensor is full of liquid during the process of Zero Calibration.
• Carry out the Zero Calibration of the flowmeter.

The user can detect a fault in the flowmeter using the LED indicator and LCD displays. Different colors of the
LED lights indicates the working condition of the flowmeter, while the LCD displays can show the self-diagnos-
tic alarm information of the transmitter, which is useful for detecting the malfunctions.
