Description
5 DESCRIPTION
5.1 Area of application
The insertion electromagnetic flowmeter type 8045 is intended exclusively to measure flow rates in liquids.
The device makes it possible to switch a solenoid valve or activate an alarm thanks to a transistor output and,
for some versions, by means of two relay outputs, fully configurable and to establish a control loop thanks to a
4...20 mA current output.
The versions also equipped with a digital input make it possible to remotely activate a function.
5.2 General description
The device comprises both a flow sensor operating on Faraday's law and a transmitter with display.
The device is equipped with a 4...20 mA current output (analogue output, called AO1), a digital output (con-
figured as a pulse output by default, called DO1) and two totalizers.
Some versions are equipped with two relay outputs (called DO2 and DO3) and one digital input (called DI1).
The device operates on a 3 wire system and needs a 18...36 V DC power supply.
The electrical connection is made on the terminals blocks of the electronic board within the transmitter, through
two M20 x 1,5 cable glands.

Example
Flow rate
Fluid velocity
Example:
• Specification: if the nominal flow rate is
10 m3/h, the ideal flow velocity is between 2
and 3 m/s.
• Solution: intersection between flow rate and
flow velocity in the graph gives the appro-
priate pipe diameter, DN40 (or DN50 for the
asterisked fittings).
* For the fittings:
• with external thread connections acc. to
SMS 1145
• with welding end connections acc. to
SMS 3008,
DIN 11866 Rg C / BS 4825-1 / ASME BPE
or
DIN 11850 Rg 2 / DIN 11866 Rg A /
EN 10357 Rg A
• with Clamp connections acc. to SMS 3017,
BS 4825-3 / ASME BPE
or
DIN 32676 Rg A

→Respect the following additional mounting conditions to ensure that the measuring device operates correctly:
- Preferably install the device at a 45° angle to the horizontal centre of the pipe to avoid having deposits on the
electrodes and false measurements due to air bubbles (see Fig. 4);
45°

- Ensure that the pipe is always filled in the section around the device (see Fig. 5).
- When mounting vertically ensure that the flow direction is in an upward direction (see Fig. 5).

Installation and commissioning
- Prevent the formation of air bubbles in the pipe in the section around the device (see Fig. 6).
- Always mount the device upstream a possible injection point in the pipe of a high-conductivity fluid (for
example: acid, base, saline,...).

7.2.2 Installation into the pipe of a 8045 with a G2'' nut
In order to ensure a high accuracy of the measurements and good stability of the „flow zero“ point, install
the device into the processed medium at least 24 hours before calibration.

chap. 7.2.1.
→Check that there is a seal 6 on the device 1.
→Insert the nut 3 on the fitting 4.
→Insert the snap ring 2 into the groove 5.
→Position the device 1 in order the arrow on the
side of the housing indicates the direction of the
flow. The totalizers will increment.
→Insert the device 1 into the fitting 4.
→Tighten the nut 3 by hand on the device 1.
