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.

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.

How to configure a panel meter when a pressure transmitter is used?

Note: Use caution when sealing the cable at the top of the tank. There is a ventilation/reference tube located within
the cable. The purpose of this tube is provide a comparison between atmospheric pressure and the pressure that is
being exerted on the sensing diaphragm within the tank. The reference tube must be open and free to allow air to
flow back to the pressure diaphragm. Avoid blocking or bending the ventilation tube by compressing the
cable. Always keep the cable termination clean, dry and free of moisture and prevent liquid from entering the
vent tube. The LP100 Installation Junction Box comes with a Gortex breather to allow for air to pass but not
moisture. It also has the cable grip located at the bottom to secure the sensor.
INSTALLATION
The Levelpro Series is designed to operate while submerged in the actual application
liquid.Avoid installing the level transmitter along the bottom of the tank if materials such
as sludge will build up and coat/cover the transmitter.This also includes any debris that
will settle along the bottom of the tank. In these applications,it is best to suspend the
transmitter above the highest level of sludge/debris that will occur.
Location: Select a location where the temperature of the transmitter will be within
the specification of the sensor.
Position:The transmitter is not position sensitive.
Mounting:The transmitter can be mounted via several methods. It can be
suspended from the cable, it can be placed resting on the bottom of the tank in
either horizontal or vertical orientation,or it can be attached to a pipe or
hardwired using the LP100 | LCJB conduit box on the top of the housing.
Avoid installations where other tank requirements will cause the transmitter to move
or swing. Example: A mixer blade could cause the level transmitter to whip around
within the tank. An alternative would be to move the transmitter to a more stable
section of the tank or to install the Transmitter inside a still well/drop tube. This will
minimize the effects created by the mixer. Termination: The cable for the transmitter
is typically terminated at a junction box located on top of the tank. Since the vent
tube is contained within the cable, the pressure within the junction box must always
be the same as the reference (typically atmospheric) pressure for the liquid. The
inside of the function box must be clean, dry and free of moisture. (A descant can be
provided) Add the optional fitting LP100 | LCJB to complete the package. The
LP100 | LCJB features a 2" NPT thread for mounting and a liquid tight connector to
seal the cable interface, and a Gortex breather that allows for the transfer of air, but
not moisture.

After final installation of the Levelpro transmitter and its companion receiver (TruVu), no routine
maintenance is required. A periodic check of system calibration is suggested. Be sure to include a
brief description of the problem plus any relevant application notes. Contact customer service to
receive a return goods authorization number before shipping.
Maintenance should consist of inspection to see that the transmitter is free from debris and not
coated with any substance, which would prevent liquid from freely entering and leaving the
transmitter. If this occurs, the transmitter should be cleaned.
If transmitter is not functioning properly, isolate the transmitter from the system and wire as
shown below. Be sure to remove the sensor from the classified area when preforming this
test. Multi Meter should read 4 mA with the transmitter out of liquid.
1. First, verify that the sensor is wired correctly.
2. Next, check if the power supply is providing the required power.
3. Finally confirm that the loop resistance is not exceeding the sensor's specification.
