Note 4: The differential pressure transmitter should be installed at least 600 mm below the high
pressure(HP) process connection. However, this value(600 mm) may be affected by ambient
temperature, operating pressure, fill fluid or material of the wetted diaphragm. Contact
YOKOGAWA when the transmitter can not be installed at least 600 mm below the HP process
connection.
