Commissioning; Zero Point Adjustment - Siemens SITRANS F C MASS 2100 Di 3 Operating Instructions Manual

Commissioning

Before commissioning it must be checked that:
● The device has been installed and connected in accordance with the guidelines provided
● Device installed in hazardous location meets the requirements described in "Installation in
6.1

Zero point adjustment

Performing a zero point adjustment establishes the reference point of the flowmeter at zero
flow. All Coriolis sensors from Siemens are calibrated before they are sent out to customers.
However, Coriolis sensors are very sensitive, and several factors might move the zero point,
e.g. installation, pressure, temperature and even very small vibrations coming from the
process. All these factors are customer specific and cannot be simulated at the factory.
Therefore Siemens recommends carrying out a zero point adjustment before use to obtain
optimum accuracy.
In the following it is described how to zero point adjust the device. For setting application
specific parameters, please refer to the Operating Instructions of the relevant transmitter.
Before zero point adjusting
● Install shut off devices in the pipeline, optimally both up- and downstream of the sensor,
