Do not throw the package | device!
To avoid damaging the diaphragm, remove packaging and protective cap directly
before starting assembly. The delivered protective cap has to be stored!
Place the protective cap on the pressure port again immediately after disassembling.
Handle the unprotected diaphragm very carefully - it is very sensitive and may be easily
damaged.
Do not use any force when installing the device to prevent damage of the device
When placing the device into operation or after maintenance work, the probe has to be
submerged slowly into the medium! A rough immersion into the medium can damage or
destroy the diaphragm.
If there is any danger of damage by lightning or overpressure when the device is installed
outdoor, we suggest putting a sufficiently Sized overpressure protection device between the
supply or switch cabinet and the device

The warranty conditions are subject to the legal warranty period of 12 months from the date of
delivery. In case of improper use, modifications of or damages to the device, we do not accept
warranty claims. Damaged diaphragms will also not be accepted. Furthermore, defects due to normal
wear are not subject to warranty services.
TECHNOLOGY
The Levelpro pressure transmitter is placed near or on the bottom of the tank. A ceramic pressure
diaphragm within the pressure transmitter is exposed on one side to the application liquid. The other
side is exposed to the reference pressure via a small ventilation tube located inside of the cable. The
difference in pressure between liquid and reference pressures will slightly deflect the diaphragm.
The deflection of the diaphragm is measure by a built-in microprocessor located inside the ceramic
diaphragm.which is converted into a 4-20mA two wire current signal proportional the height of the
liquid.
Make sure that Levelpro Transmitter is compatible with the application liquid media.

SAFETY PRECAUTIONS
About this Manual : PLEASE READ THE ENTIRE MANUAL PRIOR TO INSTALLING OR
USING THIS PRODUCT. This manual includes information on all versions of the Levelpro
Pressure Level Transmitters Please refer to the part number located on the transmitter label to
verify the exact model which you have purchased.
User's Responsibility for Safety : Levelpro offers a wide range of liquid level sensors and
technologies. While each of these technologies are designed to operate in a wide variety of
applications, it is the user's responsibility to select a technology that is appropriate for the
application, install it properly, perform tests of the installed system, and maintain all
components. The failure to do so could result in property damage or serious injury.
Proper Installation and Handling : Only properly-trained staff should install and/or repair this
product.
Wiring and Electrical : CAUTION - Do not exceed specified supply voltage rating of 30 VDC.
Permanent damage not covered by warranty will result. This device is not designed for 120
or 240 volt AC operation. Use only the specified voltage found in the specification sections.
Temperature and Pressure : The Levelpro series are designed for use in the specified
application temperatures referred to in the specification section.
Material Compatibility : Make sure that the model which you have selected is chemically
compatible with the application liquids.
Make a Fail-Safe System : Design a fail-safe system that accommodates the possibility of
transmitter failure or battery power loss. In critical applications, Levelpro recommends the use
of redundant backup systems and alarms in addition to the primary system.

GETTING STARTED
Pressure transmitters are designed to be completely
submersed within the application fluid. The transmitters
can either rest along the bottom of the tank or be
suspended at any desired level within the tank. Please
note that the physical location of the level transmitter
will indicate the lowest level of measurement within the
tank. For example: mounting the transmitter 2 feet from
the bottom of the tank, then the lowest reading of liquid
will be 2 feet from the bottom.

How to convert Pressure into Liquid Height?
Pressure transmitters are all defined by the pressure range or
distance range. To convert pressure to Liquid Height, use the
following ratio:
1 psi = 2.31 feet of water
or
1 psi = 0.704 meters of water
10 psi x 2.31'/psi = 23.1'
or
23.1'/2.31 = 10 psi
Therefore,a 10 psi transmitter will have a
Liquid Height = 23.1 feet
With the above ratio, you can always find the Liquid Height or
Water Column (wc) of any Levelpro pressure transmitter

Water has a SG = 1.0.
A SG <1.0 required more liquid (a taller water column) to equal the same pressure or height as with water.
A SG >1.0 requires less liquid (shorter water column) to equal the same pressure or height as with water.
SG = .0
Water H20 SG = 1.2SG = 0.9
How does Specified Gravity affect pressure transmitters?
The Specific Gravity (SG) of a liquid will not change the pressure of the transmitter, but will affect how
the transmitter reads the liquid height. Remember, liquids with a SG < 1.0 are lighter than water
ex.Oil and liquids with a SG > 1.0 are heavier than water ex. Sulphuric Acid

Levelpro sensors are provided in distance measurement ranges i.e. 0-14 ft, 0-20 ft, 0-33 ft etc. To
calculate the maximum range or the liquid that a particular sensor will measure, use the following
Example : 0-14 ft transmitter installed in a liquid with a maximum height of 12 feet and a SG=0.9 will
have a Sensor Height with a range 0-14' = 14 feet /0.9 = 15.5'…so it can measure more liquid than
the 14' range due to the SG being below 1 (H20 water)
Example : Compare the Maximum Liquid Height of a liquid with a SG = 1.5.
SG = 1.5: 0-20' Range transmitter will have a Maximum Sensing Height (Liquid) = 20/1.5 = 15 ft
SG = 1.0: 0-20' Range transmitter will have a Maximum Sensing Height (Liquid) = 20/1 =20 ft
When the Specific Gravity is less than 1.0, the Maximum Liquid Height of the transmitter will
increase. The reverse is true by increasing the Specific Gravity. With a SG = 1.5, the Maximum
Sensing Height (Liquid) = 15' with a Transmitter with a Range of 0-20 ft Transmitter
Note: Identifying the correct specific gravity for the fluid is critical in understanding the
operational range of the pressure transmitter.
Maximum Liquid Height (feet) = Maximum Liquid Height of Liquid / SG

This method works with the Levelpro Series level displays & controllers . These panel meters are
configured using the linear SCALE function. The settings are as follows:
Remember, pressure transmitters are configured so 0 psi/ft = 4mA | 0.5V and the maximum psi/ft =
20mA | 4.5V. Levelpro pressure transmitter applications will not use the full range of the
transmitter. Therefore, a full tank will typically have a current less than 20mA | 4.5V.
Note: The values for empty and full represent what the display will show when the tank is
either Empty or Full. Empty and Full must be the same units ex: Gallons, Inches,
percent.
