Speed sensor calibration
VISIO MULTIFLOW calculates the information concerning the speed thanks to pulses received by the sensor installed on the wheel.
To perform speed sensor calibration, proceed as follows:
-Measure a straight path at least 100 m (300 feet) long.
The longer the distance traveled, the more accurate the wheel constant calculation.
- Take measurements with tyres at the operating pressure.
This test must be performed on medium-hard terrain; for application to very soft or very hard terrain, rolling diameter may vary, leading to inaccurate output
calculation; when this is the case, repeat the procedure.
During the test, cover the distance with the tank filled up to half capacity with water.
9.2.3
Manual calibration
Manual calibration allows to enter the wheel constant value calculated with the suitable formula:
Kwheel =
distance traveled (cm)
no. of detection points x wheel rpm
<distance traveled>
distance expressed in cm covered by the wheel along measurement travel;
<no. of measurement points>
number of measurement points (e.g., magnets, bolts, etc.), mounted on wheel;
<no. of wheel revolutions>
number of wheel revolutions required to travel measurement distance.
The wheel constant can be calculated with a good approximation by detecting the distance traveled by the wheel with the speed sensor.
