SYSTEM DESCRIPTIONS  
1
GENERAL DESCRIPTION  
The LVUN-600 Series Liquid Level Detection system is an ideal, low cost ultrasonic  
liquid level detection system for many applications. It operates in a broad spec-  
trum of viscous to light liquids.  
PRINCIPLES OF OPERATION  
2
PRINCIPLES OF OPERATION  
The LVUN-600 Series operates using ultrasonic sound wave propagation. Ultrasonic  
sound waves are greatly attenuated when transmitted through air. Conversely,  
when liquid is present, transmission of the sound waves is greatly enhanced. The  
electronic control unit, either integral or remote to the sensor, generates electrical  
signals that are converted to bursts of ultrasonic energy at the sensor. The ultra-  
sonic bursts are transmitted across the liquid sensing gap of the sensor. Upon  
receipt of a valid signal at the receiver, the solid state electronics generate a “data  
enable” condition indicating liquid is present. This signal energizes a relay and  
provides an output condition.

INSTALLATION  
3
GENERAL INSTALLATION  
All units are easy to install. The sensor with its remote electronic control unit can  
be mounted in any position or orientation desired.  
Make sure that all wiring, conduit and electrical fittings conform to local electrical  
codes for the location selected.  
VISUAL INSPECTION  
Unpack the control unit and sensor assemblies. Visually inspect them for any  
damage. Advise Cosense immediately if either assembly is damaged.  
PRELIMINARY OPERATIONAL CHECK  
Before installing the unit, a simple operational checkout should be performed as  
follows:  
WARNING: In a hazardous environment never open the housing cover or con-  
nect the power leads without first disconnecting the electrical power at its  
source.  
1. Fill a container with liquid.  
2. Open the control unit housing cover and connect the power to the control unit  
(see wiring diagram).  
3. Apply power from the source.  
4. Place the sensor in the liquid. The relay should energize.  
5. Remove the sensor from the liquid. The relay will de-energize indicating that  
the system is functioning properly.  
6. Disconnect the power to the control unit.  
7. Proceed to final installation.  
NON-INVASIVE / CLAMP-ON TIME  
Refer to the typical installation diagram and follow the instructions below.  
1. Clean the mounting surface of the pipe or vessel.  
2. Coat the sensor faces and the area on the pipe or vessel where sensors are to  
be mounted liberally with coupling compound (silicone grease or heat sink  
compound).  
3. Clamp the sensor assembly on the pipe or vessel. Tighten the clamp assembly  
on the vessel until the sensor assembly is firmly mounted against the sensor  
wall. Do not over tighten.  
4. Run the cable to the control unit assembly.

CONTROL UNIT  
Refer to the typical installation diagram and control unit dimensions when  
installing the control unit.  
CALIBRATION PROCEDURE  
After the installation is complete, the system must be calibrated for proper opera-  
tion.  
1. Connect the sensor cable to electronics as shown in wiring diagram.  
2. Connect power as per wiring diagram.  
3. Turn the power on.  
4. Allow the liquid to rise above the sensing point until the relay is energized.  
5. Allow the liquid to fall below the sensing point, relay should de-energized.  
6. Repeat steps 4 and 5.  
7. Unit is now calibrated. When the liquid level is above the sensing point, the  
relay will be energized. When the liquid level is below the sensing point,  
the relay will be de-energized.  
MAINTENANCE  
PREVENTIVE MAINTENANCE  
Electronics are constructed with solid state components.  
Periodically, check and clean the sensor(s) when used with  
liquids which cause a coating to build up on the sensor. No  
other maintenance is required.  
CLEANING  
If the pipe or vessel to which the sensor is mounted is to be steam cleaned or  
cleaned with abrasive detergents, remove the entire unit before cleaning by:  
1. Disconnecting the power at source.  
2. Opening the housing cover.
