MICROFLEX LR LONG RANGE LEVEL TRANSMITTERS

GENERAL DESCRIPTION
The Microflex LR –Integral Transmitter is capable of non-contact level
measurement over distances of up to 60 metres, depending on the
application. The Integral is an intelligent, system approach to measurement
of solids and liquids with maximum performance combined with a display and
keypad.
The Integral is available with four different transducers for ranges of 10, 20,
40 and 60 metre operation. Each configuration is available as a 2-wire, DC
powered 4-20mA loop (MI2) or 2, 3 and 4 wire DC and AC powered (MI3)
with a combination of Modbus, 2 relays, 4-20mA and PC comms outputs.
The transmitter must be mounted directly above the surface of the material to
be monitored.
Ultrasonic pulses are transmitted to the surface of the material to be
monitored and reflected back to the transmitter. The time period between
transmission and reception of the pulses is directly proportional to the
distance between the transmitter and the material.
Since the speed of sound through air is affected by temperature, a
temperature sensor is integrated into the face of the transmitter to improve
accuracy.
The Integral transmitter is suitable for measuring the following on solids and
liquids:
a) Ullage space or distance to material
b) Material level
c) Volume measurement
d) Material percentage
e) Flow of liquids in open channels
WARNING
Do not open the transmitter terminal cover or remove
any connection whilst the power is ON.

1.1 Microflex LR Integral
The Integral Transmitter is an easy-to-use level
transmitter available with four (4) different high
power, low frequency front ends, capable of reliably
tracking the level of solids and liquids under difficult
conditions, programmed via a 4 button keypad and
an integral menu driven display.
The transmitter is available with a choice of 2 relay
switches, 4-20mA or Modbus outputs; up to 32
instruments can be networked together.
If specified, the instruments are available approved
for ATEX EEx ia Zone 0 gases & Zone 20 dusts
(24Vdc only) or ATEX Dust Protection only, Zone
20.
Remote programming of the product is available via
Hycontrol’s Vision System II software and all the
instruments can be connected via the Hycontrol
Link to a Service Engineer in the Redditch office to
analyse and overcome any problems which may be
experienced in the field, without incurring any
expensive call-out charges.

INSTALLATION GUIDE
The Integral transmitters are designed to be screwed directly into a flange on a
tank. For long range and dusty applications, the use of a focaliser on the
underside of the flange improves the concentration of the signal and ensures
that spurious signals are eliminated.
2.1 Installation Position
Ensure that the mounting surface is not subject to vibration and is not in close
proximity to high voltage power cables, contactors or drive controls. The unit
should not be mounted in a confined space where temperature might exceed
the safe working temperature –20°C to + 60°C*. If the unit is mounted outside
it should be protected from direct sunlight or severe weather conditions.
When using a focaliser cone, ensure that it protrudes at least 50mm into the
vessel.
The transmitter must be installed to ensure a clear line of sight from the
radiating face to the product being monitored. Refer to diagrams on Page 6.
Avoid mounting near fill points, ladders, baffles, agitators etc.
