After installation of the flow sensor in the pipeline, the following must be checked:

- According to the name plate, if there is a relevant meter in the given measuring point

(pressure, temperature, dimension, etc.).

- If the direction of the arrow on the device is in agreement with the direction of the

flow in the pipeline.

- Correct position of the measuring electrodes (horizontally).

- Accuracy of flow sensor earthing.

- Accuracy of execution of the pipeline calming section lengths

- If the sensor is protected against vibrations and mechanical damage.

Workers performing wiring are subject to the requirements of Decree No. 50/1978 Coll. on

activities on electrical equipment!!!

When the following operations are performed unprofessionally, the claim on warranty for the

resulting errors becomes extinct!!!

Prior to any manipulation with the meter, switch off the power!!!

Evaluation unit

As a standard, the evaluation unit is delivered for 24V DC±15% /250mA power supply.

The flow meter signal outputs must only be connected to devices where accident protection is

provided by safe low voltage and where generated voltages do not exceed the limits defined

for safe low voltage.

Electrical connection of the meter is carried out by means of 8-pin M12x1 connector

All signals are active.
