Tank Level Sensing Processor and Sensors 1 Introduction Congratulations on your purchase of the Tank Level Sensing Processor and Sensors from B&G. The system is designed to supply the user with reliable data on tank levels and volumes, making for accurate monitoring of on-board fluids, essential for precision trimming to achieve optimum performance when it counts.
Tank Level Sensing Processor and Sensors 4 Description The Tank Level Sensing Processor and Sensors from B&G offers a choice of 5-bolt tank insert fittings in either brass, stainless steel or marine-grade aluminium, and can be mounted in a tanktop position or on the tank side if space is limited. Using SWAGELOK fittings the tank unit is connected to a Sensor Module by 7.5mm (¼ inch) diameter tubing. A length of 7.

Tank Level Sensing Processor and Sensors 7 Setup 7.1 Configuration 7.1.1 Sensor Inputs The TLSP has the ability to accept inputs from up to 12 sensors. In the majority of cases not all 12 will be used so the TLSP will require configuration in order that it should know which tank input controls which tank function. ú ú ú ú Scroll to the ‘TANKS’ menu on the FFD, press ENTER. Scroll to ‘CONFIG’, press ENTER. Scroll to ‘CALIBRATE’ on the opposite side of the display.
Tank Level Sensing Processor and Sensors An example is shown, setting tank 4 input. SF BAL PC 7 5 .3 4 TK4 TXT To avoid confusion, it is not possible to assign the same text to 2 different sensor inputs. If the text is changed, the sensor input associated with that text will change to display TANK xx, until it’s CAL VAL 4 is also changed. If CAL VAL 4 is set to 0, TANK xx will be displayed.
Tank Level Sensing Processor and Sensors To change the displayed units for each sensor: ú ú ú ú ú ú Scroll to the ‘TANKS’ menu on the FFD, press ENTER. Scroll to highlight the tank to be changed, press ENTER. Scroll to ‘CALIBRATE’ on the opposite side of the display. Press ENTER so that ‘CAL VAL1’ is flashing. Press ENTER, the current setting for the units is shown. To change the units press ENTER, change the value, press ENTER again to confirm.
Tank Level Sensing Processor and Sensors To Calibrate ‘FULL’ • • • • Ensure that the tank is full and all connections are secure; check that the yellow flame resistant tubing is connected to the Sensor Module, (refer to the Note on Page 12 of this manual). Scroll to ‘CAL VAL 3’ (Full Vol). Press ENTER, the default maximum value is displayed. To set the maximum level, press ENTER and scroll up to set the value, which is the maximum tank capacity (e.g.
Tank Level Sensing Processor and Sensors 8.2.3 Overview The software will support up to 10 incremental steps for calibrating the volume of your tank, however for the examples below, six stages have been chosen: Empty, Full and four intermediate levels. The readings from the sensor are then interpolated between these known values to give an accurate representation of the quantities of liquid in the tanks at any given point.
Tank Level Sensing Processor and Sensors In the case of a very irregular tank it would be sensible to bias the calibration points in the area around the irregularity, as detailed in the example below: 6 (Full) 5 4 3 2 1 (Empty) Irregular Shaped Tank Section The readings obtained from the tank may be ‘damped’ to reduce any oscillation in values as the water moves in the tank. The duration of the damping can be changed via the system displays. (Refer to Para 10).
Tank Level Sensing Processor and Sensors 8.3 Calibration Procedure To start the PC utility: ú ú ú ú Ensure that the Tank Monitoring Processor is connected to one of the PC’s COM ports (COM port numbers over 8 are not recognised by the software) Ensure that the B&G system power is switched on. Start the B&G Tank Monitoring System PC Utility on the PC. The software will identify the COM port and establish communication with the Tank Monitoring System.
Tank Level Sensing Processor and Sensors • • • • If the tank is Disabled then it can be Enabled by clicking the “Enable Tank” button. Note that you can only enable tanks in sequence (enabling tanks 1,2,3 and 4 is accepted. Enabling tanks 3,4,8,11 is not for example). To change the name of a tank click the “Change Tank Name” button and enter the new tank name. Press OK to accept or Cancel to discard. To set the units displayed select the appropriate option from the “Units ” drop down box.
Tank Level Sensing Processor and Sensors 9 Alarms Once the system has been correctly calibrated the system will display the levels of the tanks in the units desired. The system allows the user to set alarms and alter the damping value. Each enabled tank sensor may have a minimum and maximum alarm threshold set to it. When setting the alarm, the threshold level is in the same units as the displayed reading; i.e. if Tank 1 is in gallons then the alarm value will also be in gallons.
Tank Level Sensing Processor and Sensors 11 NMEA Output To allow other equipment to interface with the TLSP, a NMEA sentence is transmitted showing the levels in the tanks. The messages are transmitted using the XDR sentence. Each tank output will have a separate NMEA message. The format for the XDR message is below: $YXXDR,V,0.095,M,1 P F BAL *HH Label Text Sensor Input Number Measurement Units Measurement Data Transducer Type From the NMEA specification, the Talker ID is YX (Transducer).
