Technical Questions

Q/   What does 1% accuracy really mean.

A/  1% is the overall accuracy of the Gauge. If the tank is a 10,000 litre tank, 1% is 100 litres.This is at any time or position in the tank. This is combining Linearity, Thermal affects and overall accuracy.

Q/    Why would I buy a T5020 instead of a C2020. 

A/     If you need RS485 Modbus RTU communications with Building management system (BMS) or Fuel Management systems,  then the "T" series may be required.

A/     If you are looking for 0.5% accuracy or better then the T4020 and T5020 series are better suited.

Q/   How far can I mount the display box (Gauge) from the Sensor.

A/   Up to 100 meters when using the C series voltage sensors and low loss cable (see "CABLE-4-BLACK).  Up to 200 meters when using the A and B series "milliamp sensors" (see CABLE-$-BLACK)

NOTE  :  JUNCTIONS SHOULD BE VENTED TO ATMOSPHERE

Q/   How much current does the unit draw?

A/   80 mA

Installation Questions

Q/     How do I set the Span up for the Tank sensor.  Tank sensors are C22, C23, C25 and C27

A/     Scroll through to section 10 amd 11 of the set-up sheet and make the span match the sensor range 

Q/     Why does the Gauge read lower than we expected.

A/     If the sensor is 50 mm off the bottom, check this OFFSET has been set in Sensor Settings screen.  (Sensor Settings screen is accessible in the Calibration mode)

A/    Check the specific Gravity is correctly set. (The gauge is shipped with SG = 1.00)

A/    The sensor Max setting can be adjusted downwards in steps of 0.05 volts to improve accuracy. (Min set 4.3v) 

Q/    Why does the Gauge read Higher than we expected.

A/   Is the tank size set, the inner tank size or the outer tank size

A/   If the sensor has been installed on the bottom of the tank it should be raised to 50 mm ( Unless in AdBlue or other water based liquids)

A/   The Sensor Max setting can be adjusted upwards in steps of 0.05 volts to improve accuracy. (Max set 4.7v).  This will bring the Gauge reading down a little.

Q/    The Gauge reads full, and does not register and changes.

A/   The guage when over 100% will not change readings. Lift the sensor a little to see the level falls if you are in doubt. Check the tank height for accuracy of input measurement.

A/   If only two wires from the probe are connected it will read full on a voltage sensor.
