Sensor Installation
When installing the sensors, use only non-corrosive fastening materials and fasten the
sensors both securely and tightly.
To avoid disturbances from electrical interference, do not locate
sensor cables close (or parallel) to an engine (motor) or main
power lines.
Combi Sensor
Fasten the sensor through the four holes on the front and reverse sides of the ground
plate (Figure 6-12, detail Y). Use the slotted holes (Figure 6-12, detail X) to snap the
sensor onto a special base plate (Type BST) for use in conjunction with the pipe
mounting system. Never use the slotted holes to install the sensor with screws or
similar fasteners.

To install the combi sensor on the pipe bottom, use 4 stainless steel screws of
sufficient length (between 1.18 and 2.76 inches (30 and 70 mm)) with the
accompanying dowels. ADS does not recommend using studs or similar bolts.
Determine the length of the screws based on the consistency and integrity of the
structure to which the sensor will be secured. Choose an adequate length to ensure
the sensor can be safely and securely fastened and the installation will remain durable
under any operational conditions.
Screws and fasteners extending into the flow can introduce
turbulence or build-up in a wastewater environment, potentially
resulting in erroneous flow measurements. Therefore, use well-
fitting, counter-sunk screws and screw them completely into the
mounting plate so they are as flush as possible with the plate.
Install the sensor at the bottom the center of the pipe (unless instructed otherwise by
ADS) with the beveled side facing upstream toward the oncoming flow.
When using a combi sensor with simultaneous water-ultrasonic depth detection,
install the sensor parallel with the flow surface and no more than ±2 ° from the
