Important note

Non-compliance can result in malfunctions or interference�

2 Safety instructions

• Please read this document prior to installing the unit� Ensure that the product is

suitable for your application without any restrictions�

• Improper or non-intended use may lead to malfunctions of the unit or to un-

wanted effects in your application�

• That is why installation, electrical connection, set-up, operation and mainte-

nance of the unit must be carried out by qualified personnel authorised by the

plant operator�

• In all applications test the compatibility of the product materials (→ 12 Techni-

cal data) with the media to be measured�

For units with cULus approval and the scope of validity cULus:

The device shall be supplied from an isolating transformer having a secondary

Listed fuse rated as noted in the following table�

Overcurrent protection

Control-circuit wire size Maximum protective device rating

22 (0�32) 3

20 (0�52) 5

18 (0�82) 7

16 (1�3) 10

The Sensor shall be connected only by using any R/C (CYJV2) cord, having suit-

able ratings�

3 Functions and features

The unit monitors liquids�

It detects the 2 process categories volumetric flow and medium temperature�

Applications:

• Water

• Glycol solutions

• Oils (viscosity: ≤ 68 mm²/s at 40°C)

Selection of the medium to be monitored → 9�4�8�

4 Function

4.1 Processing of the measured signals

• The unit displays the current process values�

• It generates 2 output signals according to the parameter setting�

- OUT1: analogue signal for temperature�

- OUT2: analogue signal for volumetric flow�

4.2 Volumetric flow monitoring

The flow rate is monitored by an ultrasonic meter, the measured signals by the

electronics�

• An analogue signal proportional to the volumetric flow (4��20 mA) is provided

on output 2� For the analogue functions → 4�4�

4.3 Monitoring of temperatures

• An analogue signal proportional to the temperature (4��20 mA) is provided on

output 1� For the analogue functions → 4�4�

4.4 Volumetric flow or temperature monitoring / analogue

function

• The analogue start point [ASP] determines at which measured value the output

signal is 4 mA�

• The analogue end point [AEP] determines at which measured value the output

signal is 20 mA�

Minimum distance between [ASP] and [AEP] = 20 % of the final value of the

measuring range�

MEW = final value of the measuring range

In the set measuring range the output signal is between 4 and 20 mA�

It is also indicated:

Volumetric flow above the measuring range: output signal > 20 mA�

4.5 Customer-specific calibration

This calibration changes the slope of the curve of measured values for volumetric

flow� It influences the display and the outputs�

5 Installation

5.1 Installation location

► Install the unit in that section of the plant where the medium flows under pres-

sure� This avoids disturbance by air bubbles�

► Install the unit so that the measuring pipe is always completely filled�

Arrange for inlet and outlet pipe lengths� Disturbances caused by bends,

valves, reductions, etc� are compensated for�

It applies in particular: no shut-off and control devices are allowed directly in

front of the unit�

S = disturbance; D = pipe diameter; F = flow direction

► Install in front of or in a rising pipe�



F = flow direction

► Avoid the following installation locations:

• Directly in front of a falling pipe�

• In a falling pipe�



F = flow direction

• At the highest point of the pipe system�

• Directly in front of the spout of a pipe�



F = flow direction

• On the suction side of a pump�



F = flow direction

5.2 Installation position

Avoid the following installation position: flow direction horizontal, unit vertical,

connector upwards� There is the risk of build-up of air bubbles� This can affect the

measuring accuracy�



F = flow direction

5.3 Installation in pipes

The unit is installed in the pipe using adapters� Adapters have to be ordered sepa-

rately as accessories�

Order no� E40205: 2 adapters G 1¼ for 1“ pipes, stainless steel + 2 seals�

1� Screw the adapter (B) into the pipe (A)�

2� Place the seals (C) and install the unit according to the marked flow direction�

3� Screw the adapter (B) with the threads (D) until it is hand-tight�

4� Tighten the two adapters in opposite direction (tightening torque: 30 Nm)�

After installation air bubbles in the system can affect the measurement� Help:

► Rinse the system after installation for ventilation (rinsing quantity

> 20 l/min�)�

5.4 Protection against high medium temperatures

For medium temperatures over 50 °C (122 °F) some parts of the housing can heat

up to over 65 °C (140 °F)�

► Protect the housing against contact with flammable substances and uninten-

tional contact�

6 Electrical connection

The unit must be connected by a qualified electrician�

The national and international regulations for the installation of electrical

equipment must be adhered to�

Voltage supply to EN50178, SELV, PELV�

► Disconnect power�

► Connect the unit as follows:
