7. WARRANTY CONDITIONS

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.

ContinuousSubmersibleLevel Transmitter

Levelpro-Sensors Manual

8. 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.

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 (Oil) and liquids with a SG > 1.0 are heavier than water. (Sulphuric Acid)

GETTING STARTED (Continued)

How does Specified Gravity affect pressure transmitters?

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

1 psi = 0.704 meters of water

10 psi x 2.31'/psi = 23.1'

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

SG = .0 (Water H20) SG = 1.2SG = 0.9

1 psi

2.31 Feet (S.G.)

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.

ContinuousSubmersibleLevel Transmitter

Levelpro-Sensors Manual

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 formula:

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:

GETTING STARTED (Continued)

Settings Default Represents Typical Setting

Input 1= Empty 4.0 Input Current @ Empty 4.0mA

Input 2 = Full 20.0 Input Current @ Full 20.0mA

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

Remember, pressure transmitters are configured so 0 psi/ft = 4 mA and the maximum psi/ft = 20 mA. Levelpro pressure transmitter

applications will not use the full range of the transmitter. Therefore, a full tank will typically have a current less than 20 mA.

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 (example: Gallons, Inches, percent).

9. 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 conduit

box on the top of the housing.

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.

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 LP 100 to complete the package. The LP 100 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 4mA 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.
