1.4 Structural Considerations
(1) The register is of weather tight construction for
outdoor service.
(2) Do not attempt to replace component parts with
substitutes or perform any unauthorized circuit
modification.
(3) The cable lead-in supplied with the explosionproof
type forms part of the flameproof enclosure. Do not
attempt to use any substitute lead-in other than those
supplied. The pressuretight packing union should be
tightened securely upon completion of connections.
• Output provided: ......... Other than 00 in the last
two digits of product code ... Pressuretight
packing is supplied (Excluding ATEX and FM
explosionproof products).
• Output not provided: 00 in the last two digits of
product code .......... Close-up plug is supplied.
(4) Of the four different pressuretight packings (
φ
9,
φ
10,
φ
11 and
φ
12) furnished as standard
accessories, a
φ
11 packing is tentatively
installed in place.
Select from these and install the one that best
fits the finished outside diameter of your
particular cable.

CAUTION: Moisture intrusion into the

performance problem.
2. OPERATING CONDITIONS
To maintain the stated high accuracy and long
service life of OVAL UF-II flowmeter, make sure that
flowrate, pressure, temperature and viscosity are
held within the ratings shown in the nameplate
attached to the top of the register.
Do not fail to confirm these ratings before placing it
in service.
CAUTION
1. Although allowable ambient temperature is up to +60
°
C for explosionproof units, it is
desirable that the meter be used at room temperature and humidity.
2. In cases where the register is exposed to elevated temperatures due to exposure to direct
rays of the sun or to radiant heat, ensure, by providing a sunshade or similar protection,
that the meter is used within the operating temperature range.
3. Standard ULTRA register is not provided with subtract function. If pulsation in the flow
(where the fluid moves back and forth in the pipeline under the influence of pressure)
or reversal of flow exists, the total counter may show erratic reading, accumulating all
incoming pulses irrespective of flow direction.

NOTE: Cable gland is not supplied with non-
explosionproof type models. The
customer is to prepare a watertight
gland (thread size: G

provide means to preclude moisture
from the register.

(5) In case of ATEX or FM approvals:
Where ATEX or FM explosionproof specification is
selected, make sure to use cable gland complying
with the certified standards respectively.
