The ISC40 sensor type -GG and -TG are supplied with a Viton gasket. This gasket may be used with the older series of ISC40FF fittings. It should be discarded when the sensor is mounted in combination with the ISC40FF type -PA and -FA.
2.2 INSTALLATION OF ISC40 SENSOR IN ISC40FF Installation of the flow fittings involves two steps: • Installation of the sensor The sensor has to be mounted in the flow fitting. It is important that the position of the sensor in the fitting allows easy flow through the hole of the sensor donut (refer to Section 3 of ISC40 manual).

3.2 INSTALLATION OF ISC40 SENSOR IN ISC40FS The key difference between a sensor adapter and a subassembly is, that with subas- sembly installation the sensor can be removed from the process installation without removing the subassembly first. This allows easier access to the sensor for mainte- nance activities.
