Function and features

The flow monitor monitors liquid media. It senses whether there is a preset flow (= medium flows) or not (= medium does not flow) and provides a switching signal.

Installation

1. Weld the adapter into the pipe. The installation depth depends on the pipe wall thickness. The bush should be inserted so that the figure corresponding to the wall thickness is flush with the outside pipe wall and can be seen from all sides (fig. 1a).

In the case of horizontal pipes the bush should be welded at an angle of 45^ (fig. 1b).

To avoid malfunction a minimum distance between the flow monitor and bends, valves or such like must be observed (fig. 3).

• Min. 5 x pipe diameter upstream,
• Min. 3 x pipe diameter downstream.

1. Insert the flow monitor into the bush by means of lock nut, O-ring seal and compression washer and screw it in completely using the full thread (fig. 2a, 2b).

1. Position the flow monitor (in the longitudinal pipe axis or transverse to it, fig. 3a) and fasten the lock nut (fig. 3b).

Electrical connection

The unit must only be mounted by an electrician.

The national and international regulations for the installation of electrical equipment must be observed.

Voltage supply for units up to 60 V to EN50178, SELV, PELV.

Isolate power, then connect the unit (see page 3 or type label).

Adjustment

chain of LED's

• red LED lights: the unit is not adjusted
• yellow LED lights: the output is switched

• green LED lights: the unit is adjusted

• Apply the operating voltage. Switch on the flow (preset value) and keep it constant.

The yellow LED lights; the output is switched for about 20s (power-on delay time).

1. Turn the pot until one green LED comes on. The farther the green LED is away from the yellow LED, the safer is the adjustment (excess gain for flow or temperature fluctuations).
2. Conceal the pot after adjustment by the label provided to protect it against unauthorised tampering.

Operation

After mounting, wiring and setting check whether the unit operates correctly.

Recommended maintenance

Check the sensor tip for build-up from time to time. Clean it with a soft cloth. If necessary, build-up which adheres firmly (e.g. lime) can be removed with a common vinegar cleansing agent.

The units are suitable for use in moderate electromagnetic fields (see table). When operating ISM equipment or powerful walkie-talkies in the vicinity of the units additional measures to avoid malfunction can be required.
