Electromagnetic Flow Transmitter
The electromagnetic flow meter Type 8045
has been designed for pipes with diameters
ranging from DN 06 to DN 400 and liquids
having a conductivity > 20 µS/cm.
The transmitter has a display, a keyboard and
provides 4-20 mA, relay and pulse outputs;
The version with a stainless steel sensor has
been designed for applications with high
pressures (PN16) and high temperatures (up to
110°C).
The version with Alloy C22 electrodes has
been designed for applications with aggressive
fluids (chemicals) and especially sea water ap-
plications.

Possible applications
Flow control of fluids, contaminated or not:
Waste water treatment
Flow control of drinking water (FDA approval)
Laundries: measurement and control of the water consumption
Swimming pools: pump protection and flow control
Food-processing industry: monitoring of the cleaning cycles (FDA approval)
Irrigation
Application with sea water: desalination, fish farms
Design
The E-shaped magnetic system inside the sensor induces a magnetic field into the fluid, which is perpendicular to the
direction of flow. Two electrodes are in galvanic contact with the liquid. Based on the Faraday law a voltage can be
measured between these electrodes once a liquid (min. conductivity of 20 µS/cm) flows along the pipe.
This voltage is proportional to the flow velocity.
Using the K-factor for the individual pipe diameter the speed of flow is converted into volume per time.

Installation
The 8045 transmitter can easily be installed into any Bürkert
INSERTION fitting system (S020) by just fixing the main nut.
Minimum straight upstream and downstream distances must be
observed. According to the pipe’s design, necessary distances
can be bigger or use a flow conditioner to obtain the best accu-
racy. For more information, please refer to EN ISO 5167-1.
EN ISO 5167-1 prescribes the straight inlet and outlet distances
that must be complied with when installing fittings in pipe lines
in order to achieve calm flow conditions. The most important
layouts that could lead to turbulence in the flow are shown be-
low, together with the associated prescribed minimum inlet and
outlet distances. These ensure calm, problem-free measurement
conditions at the measurement point.
It is advisable to mount the transmitter
at a 45° angle to the horizontal centre
of the pipe to avoid having deposits
on the electrodes and false measure-
ments due to air bubbles.
The flow rate transmitter can be installed into either horizontal or
vertical pipes. Mount the 8045 transmitter in these correct ways
to obtain an accurate flow measurement.

Pressure and temperature ratings must be respected according
to the selected fitting material.
The suitable pipe size is selected using the diagram Flow / Ve-
locity / DN.
The flow transmitter is not designed for gas flow measurement.
Example:
- Specification of nominal flow: 10 m3/h
- Ideal flow velocity: 2...3 m/s
- For these specifications, the diagram indicates a pipe size of DN40
[or DN50 for (*) mentioned fittings]
* for following fittings:
- with external threads acc. to SMS 1145
- with weld-ends acc. to SMS 3008, BS 4825 / ASME BPE or DIN 11850 Series 2
- Clamp acc. to SMS 3017 / ISO 2852, BS 4825 / ASME BPE or DIN 32676
