Level Gauge - Tanks
Features of TRACERCO™ Smart Level Gauge
- External mounting for easy retrofit or new build installation
- Intrinsic safety for use in zones 0, 1 & 2 hazardous areas
- Automatic corrections for changes in vessel operating pressure
- Linear, table and logarithmic linearization options for level
correction
- HART™ digital interface allowing direct communication via
the customer’s DCS
Benefits of TRACERCO™ Smart Level Gauge
- Provides real-time in vessel measurements
- No moving parts, eliminating the potential for mechanical failure
or fouling by debris such as sand or asphaltene
- Alarms allow high or low level liquid positions to be detected
- Reliable, maintenance free and non-contact with fluids
The TRACERCO™ Smart Level Gauge is reliable, maintenance free and
non-contact with fluids. In the case of liquid level measurement a nuclear
gauge is designed with a small source on one side that is housed in a
shielded container. The container is designed such that it emits a fan
beam of electromagnetic radiation across the vertical length of range
required. On the opposite side of the vessel a sensitive detector is positioned
within the fan bean in a vertical orientation across the span of level
range required. Using calibration data recorded within the instrument
the detector response is directly proportional to liquid level within
the vessel. The detector response is converted to a 4-20 mA and/or digital
signal and relayed to a control system. Alarms allow high or low level
liquid positions to be detected.
