1.4 Function
1.4.1Measuring principle
The transducer of the ultrasonic sensor transmits ultrasonic pulses to the product surface.
These pulses are reected by product surface and received back by the transducer as echoes.
The running time of the ultrasonic pulses from emission to reception is proportional to the distance
and hence the level.
Because the running time of the ultrasonic pulses is highly dependent on the environmental
temperature, the temperature dependent change of sound velocity must be compensated.
A temperature sensor, which is integrated in the ultrasonic sensor, is used for the temperature
measurement.
1.4.2Signal processing
The running time determined level is processed by the integrated evaluation electronic according to
the respective preferences:
• The measuring value is monitored by four PNP switch outputs for exceedance of limit values.
• The measuring value is converted into a continuous current signal 0/4...20mA or voltage signal
0…10V.
• The measuring value is diagrammed at the high brightness and high contrast TFT-LCD display,
whereby it can be selected between dierent display styles (digital value / manometer / chart / bar
graph).
• All settings can be changed comfortable and easy by a 3-key operation without additional
assistance with tactile feedback.
The device includes numerous functions to the adaption to nearly each measuring task:
• The interference echo suppression function ensures that interference echoes (e.g. from edges,
welded joints and installations) are not interpreted as a level signal.
• Integrated unit conversion
• Peak value memory minimum – maximum
• Error memory for fast failure analysis
• Various exible switch functions
• Error indication function to switch output, current/voltage output and display
• Simulation of the switch outputs and the current/voltage output
In the internal ring memory more than 500.000 measuring values can be recorded durable.
At the data logger function these measuring values are marked with a battery powered time stamp.
By the Bluetooth interface recorded measuring values can be downloaded.

3 Installation
The correct function of the device within the specic technical data can only be guaranteed, if
the permitted process and environmental temperatures (see chapter „Technical data“) will not be
exceeded.
3.1 Installation place
3.1.1Level measurement
• Do not install the sensor in the middle of the tank (C). We recommend leaving a distance between
the sensor and the tank wall (A) measuring 1/6 of the tank diameter. In vessels with conical
bottom it can be advantageous to mount the sensor in the center of the vessel, as measurement is
then possible down to the lowest point of the vessel bottom.
• Use a protective cover, in order to protect the device from direct sun or rain (B).
• Avoid measurements through the lling curtain (D). Through the action of lling, stirring and other
processes in the vessel, dense foams which considerably damp the emitted signals may form on
the product surface. If foams are causing measurement errors, the sensor should be used in a
standpipe.
• If there are strong air currents in the vessel, e.g. due to strong winds in outdoor installations or air
turbulence, e.g. by cyclone extraction, the device should be mount in a standpipe.
• Make sure that equipment (E) such as limit switches, temperature sensors, etc. are not located
within the emitting angle α. In particular, symmetrical equipment (F) such as heating coils, baes
etc. can inuence measurement. If large vessel installations such as struts or supports cause false
echoes, these can be attenuated through supplementary measures. Small, inclined sheet metal or
plastic baes above the installations scatter the ultrasonic signals and avoid direct false echoes.
• Align the sensor so that it is vertical to the product surface (G).
• Never install two ultrasonic measuring devices in a tank, as the two signals may aect each other.
• To estimate the detection range, use the 3 dB emitting angle α, which can be found in the chapter
“Technical Data - Input”. This radius of the detection range at an arbitrary distance Lx can be
calculated by the following term: rx = tan (α / 2) * Lx
Example values for Lx and rx can be found in the chapter “Technical Data - Input”.

3.1.2Installation in narrow shafts
• In narrow shafts with strong interference echoes, we recommend using a stand pipe resp. an
ultrasound guide pipe (e.g. PE or PVC wastewater pipe) with a minimum diameter of 100mm.
• Make sure that the pipe is not soiled by accumulated dirt. If necessary, clean the pipe at regular
intervals.
• The pipe must be provided with a sucient venting hole (A) (Ø 5…10mm) at the upper edge.
3.1.3Flow measurement
Example: Triangular weir
• Install the device at the inow side, as close above the maximum water level Hmax as possible
(take into account the blocking distance BD).
• Position the device in the middle of the channel or weir.
• Align the sensor membrane parallel to the water surface.
• Keep to the installation distance of the channel or weir.
ACS-CONTROL-SYSTEMGmbH l Lauterbachstr. 57 l D-84307 Eggenfelden l www.acs-controlsystem.de l [email protected] 9
3.2 Installation notes
• Drive the system pressure free prior installation resp. deinstallation of the sensor.
• The screw-in of the thread process connection by using the terminal enclosure, the connection plug
resp. the connection cable is not permitted.
• The tightening of the thread process connection may only be done at the hexagon by a suitable
spanner and with the maximum permitted torque strength (see chapter „Technical data“).
• The housing can be rotated every time, also at operation, mechanically by 300°.
• The display can be rotated every time electrically by 180°.
3.2.1Pressure / vacuum
Gauge pressure in the vessel does not inuence the measuring result. Low pressure or vacuum does,
however, damp the ultrasonic pulses. This inuences the measuring result, particularly if the level is
very low (≤ -0,2bar resp. -20kPa).
3.2.2Vapor pressure
The vapor pressure at 20°C (68°F) gives a hint on the accuracy of the ultrasonic level measurement.
If the vapor pressure at 20°C (68°F) is below 50mbar, ultrasonic level measurement is possible with a
very high accuracy.
This is valid for water, aqueous solutions, water-solid-solutions, dilute acids (e.g. hydrochloric acid,
sulfuric acid), dilute bases (e.g. caustic soda), oils, greases, slurries, pastes, etc.
High vapor pressures or outgassing media (e.g. ethanol, acetone, ammoniac) can inuence the
accuracy.
3.2.3Range
The sensor range is dependent on the measuring conditions.
The maximum range can be found in the chapter “Technical Data - Input”.
3.2.4Blocking distance
If the blocking distance is undershot, it may cause device malfunction.
• Install the device at a height so that the blocking distance BD (see chapter “Technical Data -
Input”) is not undershot, even at maximum ll level Hmax.
• If the medium reaches the transducer, buildup can form on it and cause faulty measurements later
on.

10
3.2.5Nozzle installation
Use a pipe nozzle if you cannot maintain the blocking distance in any other way.
• The interior of the nozzle must be smooth and may not contain any edges or welded joints. In
particular, there should be no burr on the inside of the tank side nozzle end.
• To minimize disturbing factors, we recommend an angled socket edge (ideally 45°).
• Note the specied limits for nozzle diameter and length.
Nozzle diameter D Maximum nozzle length L
DN50 / 2“ 80mm
DN80 / 3“ 240mm
DN100 / 4“ 300mm
≥ DN150 / 6“ 400mm
3.2.6Standpipe measurement
By using a standpipe (surge or bypass tube), the inuence of vessel installations, foam generation and
turbulence is excluded.
• Standpipes must extend all the way down to the requested min. level, as measurement is only
possible within the tube.
• The pipe must be provided with a sucient venting hole (A) (Ø 5…10mm) at the upper edge.
• Avoid large gaps and thick welding joints when connecting the tubes.
• Measurement in a standpipe is not recommended for very adhesive products.
