Ball Valve Installation Kit for HMT338
The 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 probe (ø12 mm) in a process pipe,
please note that the nominal size of the pipe must be at least 1 inch
(2.54 cm). Use the manual press handle to press the probe into the
pressurized (< 10 bar) process or pipeline.
