10.1.3 Shipping details
Package size (LxWxH) : 250 x 150 x 100 mm (9.84 x 5.90 x 3.94 inch)
Package weight (max) : 1.5 kg (3.3 lbs)
10.1.4 Process connections
1/2” NPT in flow fitting, connected with optional flange adapters to the actual installation.
Note: 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.
10.2 Installation of ISC40 sensor in ISC40FF
Installation of the flow fittings involves two steps (see Fig 18):
• 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. Generally good
flow is assured if the flats of the sensor are oriented perpendicular to the outlet piping. It
is also important that the sample piping is oriented in such a way that the direction of the
flow is upwards to assure complete filling of the flow chamber
• Installation of the fitting on wall, railing or stanchion
For this purpose the flow fitting has an optional pipe/wall mounting kit /MS or /MP (see Fig
19 for details). This kit consists of a clamp ring with bolts and nuts which clamps around
the flow chamber. Therefore the flow chamber can be turned in the mounting assembly
allowing more flexibility in installation. The mounting plate can be mounted on a wall or
panel with 2-4 anchor bolts with a diameter of 10 mm (3/8”) max. For those installations
where pipe mounting is requested (2” nominal pipe), either horizontal or vertical, a saddle
and U-bolt have to be used.
