During electrical connection of the coriolis mass flow meter you must follow the following requirements:
Wire connections must be cleaned and fixed on terminals to prevent a short circuit between each other and the body of the coriolis mass flow meter (ground);
It is recommended to use separate power supplies or a multichannel power supply with isolated channels to power the coriolis mass flow controller and each of its outputs;
If it is necessary to calculate the load resistor value, the total load impedance should be calculated as the sum of the cable resistance, external load resistance, resistance of safety barriers, load resistance of the secondary equipment;
To minimize interference when transmitting of analog output signal 4-20 mA and digital signal it is recommended to use a shielded twisted pair cable. Grounding of the cable should be provided only on one side of the cable (near the power supply);
It is not recommended to lay the signal cables in the same conduit with power wires, and also near sources of strong electromagnetic fields. If necessary, grounding of signal wiring can be done at any point in the signal circuit. For example, it is possible to ground the negative terminal of the power supply. The electronics housing is grounded to the sensor housing.
