NOTE: Before any installation work, make sure that the process pipeline is not pressurized and that the installation will be safe!
1. Pay attention to the following requirements for the installation point:
- process temperature max. 100 °C (max. 212 °F)
- pH 2.5 – 11.5
- pressure 1.5–16 bar (22–232 psi)
- do not install the sensor to the suction side of a pump
- conductivity in accordance with the sensor specifications (see App. 1)
2. Make sure that the FLOW arrow on the sensor housing is aligned with the process flow direction.
3. Make sure that the installation point and sensor position are in accordance with the instructions.
4. Protect the sensor and Display Unit from direct heat radiation (sun).
5. Make sure that the seals between the MCAi flanges and process flanges are correctly installed and the flange bolts are
properly tightened.

• When choosing the installation point, pay attention to the space required for the sensor.
• Also make sure that the Display Unit can be installed – the cable between sensor and Display Unit
is 10 m (33 ft) long.
MCAi installation points
1. NOVE is usually installed after the MCA sensor. Make sure that the distance between NOVE and MCA
is
≥
2 x D and
≥
1 x D of straight pipeline after the NOVE.
2. Install the NOVE to a vertical pipeline so that it is at a 90° angle with respect to the sensor measuring
line. Always install NOVE to a horizontal pipeline from the side.
3. If the NOVE cannot be installed after the MCA, install it to the pipeline before MCA and make sure that
there is
≥
4 x D of straight pipeline before the NOVE and
≥
1 x D after it.
