Level measurement
–
Level pulse amplitude and threshold
After connecting to a power supply, MicroTREK 2-wire will:
1.
Measure reflection pulses in terms of voltage amplitude by cycling through a set of gains.
2. Identify the highest amplitude which corresponds to the level of the medium.
This screenshot taken of the EView2, oscilloscope function while measuring while a typical single-medium measurement:
The function analyses the following data:
1 Initial pulse
2 Flange reflection (except coaxial probe)
3 Non-medium reflection (e.g. parasite: agitator)
4 Medium level reflection
5 Level threshold (with two-metre steps).
Set in 5.1.2.4.2 function.
6 Offset
(the distance travelled by the signal between the
processing unit and the reference point of the device)
7 Distance measured as a function of time
