FAQ
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.
OLE C2020 Tank Gauge c/w Probe for tanks up to 3m in height
SKU: C2020-A-C23OLE C2020 Tank Gauge c/w Probe for tanks up to 3m in height
The Basics
At a Glance
The OLE C2020 Automatic Tank Gauge, from GO Industrial, is an accurate, yet cost effective instrument to measure and report on the level of liquids within a tank. The OLE C2020 reads a hydrostatic pressure sensor that is suspended into the tank. Accuracy is +/- 1%.
We stock the C2020-A-C23 Model which is suitable for tanks 0.3 to 3 meter high. The gauge is configured with an Alarm and 4-20 mA output.
