L55 and IL55BV2 Sensor Instruction Manual
2 Installation
A reliable accurate measurement from any instrument can only be achieved by correct installation of the measuring
device, in the case of turbidity and suspended solids this is particularly important. If you are in any doubt contact your
Partech representative for advice.
Below are some points that should be considered before starting to install the sensor, and again if the results obtained
are not meeting your requirements.
•
Avoid areas of extreme flow or turbulence, air bubbles will disturb the readings.
•
The pipe, to which the sensor is fitted, is required to be completely flooded at all times.
•
There should be no rapid changes in pipe size near to the sensor installation point.
•
Do not place the sensor in an area of no flow, as the suspended solids will settle out and not provide a
representative reading.
•
Both the IL55 & IL55BV2 are removable from their mountings. It is therefore important to leave sufficient space
around the instrument so as to enable removal.
•
The sensor must be monitoring in an area that is representative of the whole process to gain accurate results.
To allow a single technician to calibrate and maintain the system the sensor should be placed within sight of the
controller. Although cable runs of up to 100 metres are possible, operational problems may be encountered.
