Ball Valve Installation Kit for MMT318
The optional ball valve installation kit (Vaisala order code:
BALLVALVE-1) is preferred when connecting the probe to a
pressurized process or pipeline. Use the ball valve set or a 1/2" ball valve
assembly with a ball hole of Ø14 mm or more.
If you install the sensor head (Ø 12 mm) in a process pipe, please note
that the nominal size of the pipe must be at least 1 inch (2.54 cm). Use a
manual press handle to press the sensor head into the pressurized (< 10
bar) process or pipeline.
