Introduction

The Solution to Tough Applications Where Ultrasonic Sensors Simply DO NOT WORK!

The TankPro® Submersible Level Transmitter provides continuous level measurement for both corrosive and non-corrosive liquids. These submersible hydrostatic transmitters have been designed for the toughest industrial applications. Unlike ultrasonic level transmitters, submersible liquid level sensors are completely unaffected by any foam, vapor, turbulence or condensate in the tank.

The TankPro® Level Transmitter comes equipped with a local LCD display and mounts on top of the tank with a 2" NPT connection. The TankPro® Series comes in PVC, PP, PVDF, PTFE Teflon® or 316 SS, making them the perfect level sensor for your chemical tank application.

Understanding Level Measurement

Submersible Level Sensor

All Submersible Sensors have a Calibrated Range which is based on H₂O that has a Specific Gravity or Density = 1.

1. Range Value: The overall measuring distance that the sensor has been calibrated to by the factory. The Range will be mentioned on the Sensor Body.
2. Empty: The pressure being exerted on the sensor diaphragm at the Lowest Point. Normally this is when the tank is empty. Empty = 4mA setting.
3. Full: The pressure being exerted on the sensor's diaphragm at the highest point liquid level within the Tank. Full = 20mA setting.

Model Selection

Getting Started

Submersible Pressure Sensors are designed to be completely submersed within the liquid. The transmitters can 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. Example: Positioning the transmitter 12" from the bottom of the tank means the lowest reading of liquid will be 12" from the bottom.

When the liquid to be measured is not H₂O, the New Range of the Sensor needs to be determined. To achieve this, simply divide the Range of the Sensor Body by the Specific Gravity of the Liquid: SENSOR RANGE / S.G = NEW RANGE.

The Importance of the Liquids S.G (Specified Gravity)

The S.G. of a Liquid has a Direct Effect on the Sensor's Output when Measuring the Height of the Liquid.

Liquids with an S.G. < 1.0 are Lighter than H₂O (e.g., Oil).

Liquids with an S.G. > 1.0 are Heavier than H₂O (e.g., Sulfuric Acid).

H₂O has an S.G. = 1.0.

S.G. < 1.0 Requires More Liquid to Equal the Same Pressure or Height as with H₂O.

S.G. > 1.0 Requires Less Liquid to Equal the Same Pressure or Height as with H₂O.

Here are some examples of how the submersible sensor range changes when submersed into liquids with different Specific Gravities:

Diagram showing a tank with water (Specific Gravity = 1).

Diagram showing a tank with acid (Specific Gravity = 2), heavier than water, requiring less volume for the same pressure.

Calculating Max. Range of a Sensor

Let's assume the calibrated range of the submersible sensor is 34" or 408". The range is always referenced to H₂O, which has a specific gravity S.G or (Density) equal to 1. Calibrated Range/S.G = Liquid Level Measurement Range. Example: 34/1 = 34' or 408/1 = Liquid Level Range = 408".

Example 1

The liquid in Tank #1 has an S.G = 0.5, which is Lighter than that of H₂O. To determine the New Range of the sensor, simply divide the H₂O Range (34') by the S.G. of the liquid that is going to be in the tank. S.G = 0.5. Calculation: 34 / 0.5 = 64 ft or 816". Since the oil is a lighter fluid than H₂O, the new measuring range of the sensor has increased and is now 64' or 816".

Example 2

The liquid in Tank #2 has an S.G. = 2, which is 2x Heavier than H₂O. The 34' sensor is now going to be installed into a tank to measure a liquid with an S.G = 2. Calculation: Range / S.G = New Range of the Sensor. 34 / 2 = 17 ft or 204".

Correct Sensor Position Setup

The Submersible Level Sensor is intended for use while fully submerged in the process liquid.

Avoid placing the sensor at the tank bottom if sludge or other materials are likely to accumulate and cover it. This includes any debris that may settle at the bottom. In such cases, it's recommended to suspend the sensor above the maximum expected level of sludge or debris buildup (see Diagram A).

Diagram A: Submersible level sensor positioned at the bottom of a tank, potentially covered by sludge.

Diagram B: Submersible level sensor suspended above potential sludge buildup.

Diagram C: Submersible level sensor positioned in a tank without sludge issues.

Avoid installations where other tank requirements will cause the transmitter to move or swing.

Troubleshooting

1. Trouble Shooting the Sensor

1. First, verify that the sensor is wired correctly.
2. Next, check if the power supply is providing the required power.

If the transmitter is not functioning properly, isolate the transmitter from the system and wire as shown in the troubleshooting diagram. Be sure to remove the sensor from the classified area when performing this test. Multimeter should read 4mA with the transmitter out of liquid.

Notes:

• The reference or capillary tube is fitted with a Gortex® Filter - this must remain attached in order to prevent moisture, particulate or insects from entering. Do Not Remove.
• Avoid Blocking or Bending the Ventilation Tube.
• The TankPro® is fitted with a Gortex® Breather to allow air to pass but not water. Please Ensure this is Not Blocked.
• Always keep the cable termination clean, dry and free of moisture to prevent liquid from entering the Vent Tube.
• Confirm Programming Input for 20mA (SE 2 on Display) is correct.
• Confirm Specific Gravity of the liquid is correct.
