Page 4

CAUTION

For medium temperatures above 50 °C (122 °F) some parts of the housing can heat up to over 65 °C (149 °F). Risk of burns.

► In this case do not touch the unit. ► Protect the housing against contact with flammable substances and uninten-

tional contact.

► Do not press the pushbuttons manually; instead use another object (e.g.

ballpoint pen).

3 Functions and features

The unit monitors water-based fluids (water, deionized water, cooling water). It detects the two process categories volumetric flow rate and medium tempera-

ture.

Pressure Equipment Directive (PED): The units comply with the Pressure Equipment Directive and are designed and manufactured for group 2 fluids in accordance with the sound engineering practice.

4 Function

• The unit detects the volumetric flow rate based on the Vortex measuring principle.

• The unit displays the current flow and temperature. It generates 2 output signals according to the parameter setting:

OUT1: 2 selection options

- switching signal for volumetric flow rate limit value

- frequency signal for volumetric flow rate

OUT2: 4 selection options

- switching signal for volumetric flow rate limit value

- switching signal for temperature limit value

- frequency signal for volumetric flow rate

- frequency signal for temperature

Page 5

4.1 Switching output

OUTx changes its switching status if it is above or below the set switching limits (flow or temperature). Hysteresis or window function can be selected. Example of volumetric flow monitoring:

Hysteresis function Window function

SP = set point rP = reset point HY = hysteresis Hno = hysteresis NO (normally open) Hnc = hysteresis NC (normally closed)

When the hysteresis function is set, the set point [SPx] is defined first and

SP = upper limit rP = lower limit FE = window Fno = window NO (normally open) Fnc = window NC (normally closed)

then the reset point [rPx] which must have a lower value. If only the set point is changed, the reset point remains constant.

When set to the window function, the upper limit [SPx] and the lower limit [rPx] have a fixed hysteresis of 0.25 % of the final value of the measuring range. This keeps the switching status of the output stable if the flow rate varies slightly.

Page 6

4.2 Frequency output

The unit provides a frequency signal that is proportional to the volumetric flow quantity and the medium temperature.

Up to the limit value set under [FEPx] (for OUT2 = TEMP: between the limit values set under [FSP2] and [FEP2]) the frequency signal is between 0 Hz and the fre-

quency value set under [FrP

5 Installation

► Flow in the direction of the arrow. Observe the installation direction.

► Make sure that pipe and sensor have the same internal diameter. ► Avoid deposits, accumulated gas and air in the pipe system. Install the unit so

that the measuring pipe is always completely filled with medium.

► Install in front of or in a rising pipe. ► Recommended tightening torque: 30 Nm ► Avoid disturbances on the inlet and outlet side. To do so, provide for the

following inlet and outlet pipe lengths:

DN = nominal width of the pipe R = radius



R1.8

≥ 0.5 x DN

Multiple bends (2 x 90°) ≥ 15 x DN Reduction of internal pipe diameter ≥ 15 x DN ≥ 15 x DN Valve or pump ≥ 25 x DN

► Mount the unit in a way that no mechanical forces are exerted on the pipe. To

do so, use angle brackets if required.

- For direct installation fix the unit on the surface utilizing the four corner holes on the underside of the unit. Mounting holes are 3.6 mm in diameter with a 57 mm x 16.5 mm on center pattern. Maximum insertion depth in the housing is 5.5 mm. Use self-tapping M4 DIN 7500 screws. Center holes are not usable due to risk of damaging sensor.

► Avoid the following installation positions:

- Directly in front of a falling pipe.

- In a falling pipe.

- At the highest point of the pipe system, when the pipe is open.

- Directly before the outlet of the pipe.

- On the suction side of a pump.

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 according to EN 50178, SELV, PELV.

► Disconnect power. ► Connect the unit as follows:
