The analog transmitter MONITOR is characterized by

reliable function and simple operation. In order to use

the advantages of this equipment in its entirety, please

consider the following:

Each person assigned to work on or operate this

equipment, must have read and understand the

Operating Instructions and in particular, the safety

references!

2.1 General information

To ensure safe operation, the device must be operated

only in accordance with the instructions in this manual.

Additionally, use of the device requires adherence to

all accident prevention-, legal regulations and safety

standards for the respective application.

2.2 Correct use in accordance

with these instructions

The analog transmitter MONITOR must only be used in

combination with the following flow monitoring- and flow

indicating devices from Meister Strömungstechnik:

DUM

DWM

RVM/U-1

RVM/U-2

RVM/U-4

DKM-1

DKM-2

DKME

DWM-L

RVM/U-L1

RVM/U-L2

RVM/U-L4

Any additional or different application, above and

beyond the correct use described in these instructions,

is deemed as incorrect use.

3 Functional description

The analog transmitter MONITOR detects the position

of magnetic floats or pistons with the aid of Hall-sen-

sors. An analog signal, appropriate to the position, is

provicled.

4 Installation

The analog transmitter MONITOR and the appropriate

flow sensor come pre-assembled. For installation into

the pipe system, please refer to the Operating Instruc-

tions for the flow sensor.

2.3 Qualified personnel

Flow monitoring/metering devices equipped with the

analog transmitter MONITOR must only be installed by

qualified personnel, who are able to correctly employ

the device for its intended purpose. Qualified personnel

are persons who are familiar with the setup, assembly,

start-up, and correct use of these devices, and who

are able to independently carry out the work assigned

to them.

Operating Instructions for analog transmitter MONITOR

-2- -3-

The device has a short-circuit proof and reverse

polarity protected switching output (Push-Pull). Analog

output 4...20 mA or 0…10 V is offered concurrently.

Programming is done with a magnetic clip through the

IP 67 enclosure. The MONITOR-electronics linearize

and convert the primary signal into a conventional

4…20 mA or 0…10 V output signal while providing

a flexible switch at the same time. Linearization and

calibration are done automatically.

6 Programming

The calibration magnet, clipped into a groove on the

device, is used to program the switch point. After

calibration, the magnet may be returned to its grooved

seat or stored elsewhere, to protect the data entered.

The calibration point is marked on the label.
