Cautions on impulse piping
• For liquid, the impulse pipes should have an upward slope of 1/10 or more between the
process connection and the transmitter to prevent accumulation of gas, etc. in the detect-
ing unit.
• For gas, the impulse pipes should have a downward slope of 1/10 or more between the
process connection and transmitter to prevent accumulation of moisture, etc. in the de-
tecting unit.
•Do not bent the impulse pipes acutely near the pressure outlet port, to prevent gas or drain
from staying in the pipe.
• Take care not to apply an excessive force to the transmitter during connection.
• In order to prevent vibration of the transmitter body and capillary from interfering with
output, the transmitter body should be installed at a vibration-free place and the capillary
should be fixed to a stable support.
• The impulse pipes used should be suitable for the working temperature, pressure, etc.
•When the measuring fluid is likely to freeze in the cover of the measurement chamber,
the cover needs to be warmed up with steam or a heater.
