5. Functions - Key Features
This HERMetic instrument is a gas-tight portable
multiple functions gauging system that is designed
to perform under completely closed conditions in a
single operation 3 measurements:
a) Ullage (outage). Optionally innage is available¹.
b) Oil/water Interface level.
Tape resolution: 1 mm (1/16 ")
Tape accuracy: ±1.5 mm for 30 m
(±1/16 " approx. for 100 feet)
Ullage/interface detection accuracy:
±2 mm (±0.08 " approx.)
Minimum detectable tank bottom interface or liquid
level: 4 mm (0.16" approx.).
c) Temperature by continuous reading at any
level.
Ambient temperature range: -20°C to 50°C
( -4°F to 122°F)
Sensor measurement range:-40°C to 90°C
( -40°F to 194°F)
Resolution: 0.01° or 0.1°, selectable
Accuracy over calibration range: ±0.1°C (0°C to
70°C); ±0.2°F (32°F to 158 °F)
Temperature reading: °C or °F, selectable.
This HERMetic device meets the requirements of
API MPMS Chapter 7 2001, table 3, ISO 4268 and
IP PMM Part IV.
Thanks to the small diameter of the sensing probe
this instrument can be used with valves of
diameters down to 25 mm (1”) only.
A tape protection tube prevents closing the valve
on the tape through inadvertence.
Gauging is done under completely gas tight
conditions therefore maintaining over- or
underpressure in the tank. The device is designed
to withstand tank pressure up to 0.3 bar (4.4 psi).
¹ An additional device, usable with 2” valves only,
can be provided that allows Reference Height
and Innage measurement. Available on “Visc”
models.
