4. Installation
4.1 Precautions
Before installing the transmitter, read the cautionary
notes in Section 2.4, “Selecting the Installation
Location.” For additional informations and
limitations according to the selected model, suffix
and option codes, please find information in each
General Specifications sheet.
IMPORTANT
• When welding piping during construction,
take care not to allow welding currents to
flow through the transmitter.
• Do not step on this instrument after
installation.
• Never loosen the four bolts securing the
cover flanges (Refer to figure 3.1.) If the seal
liquid leaks, the transmitter cannot be used.
• When installing diaphragm seals or process
connectors, make sure that no foreign matter
has adhered to the seal surface of the gasket
(or O-ring) before assembling. If foreign
matter adheres, it may lead to leaks.
4.2 Mounting
The transmitter is mounted on a process using its
high-pressure side flange as shown in Figure 4.1.
The mating flange, gasket, stud bolts and nuts are
to be procured by the customer.

IMPORTANT
When measuring the liquid level of the tank, the
minimum liquid level (zero point) must be set
to a level at least 50 mm above the center of
the diaphragm of the high pressure side of the
transmitter.
IMPORTANT
Please use a gasket with an inside diameter
(ød) that is greater than the diameter of the
diaphragm seal. If a gasket with a smaller
inside diameter is used, the diaphragm may not
function correctly.
