- Measurement Independent of Changing Densities
System accuracy is not affected by changes in temperature, density, or variations in oil level.
- Get Right to the Bottom of the Tank
Minimal dead space allows the operator to read the water level within one inch of the tank bottom. If the sensing element is located in a sump there is no dead space.
- Mounting Flexibility
Sensing element may be top mounted or side mounted.
- No Routine Maintenance
No moving parts to corrode, break down or wear out.
- Supplied with Calibration Details for Bench Calibration
Final calibration can be done quickly and accurately after installation with a known water level.
Drexelbrook's Interface transmitter can accurately measure the hydrocarbon/water (BS&W) interface location at the bottom of fuel storage tanks.
Drexelbrook’s RF/Admittance level transmitter can be used to provide water level information to a fuel management inventory system so that net gallons of Petroleum can be computed accurately. It can also be used for leak detection, where any unscheduled decrease in water level indicates a leak in the tank bottom.
The signal can also be used to control automatic water draw-off.
For installation convenience, the intrinsically-safe sensing element can be mounted through a side wall of the tank or through the roof. The specific model and measuring area (active length) of the sensing element should be specified to be consistent with the expected maximum height of the water level, mounting considerations and mounting tolerances.
Final calibration can be done quickly and accurately with a known water level on the sensing element after installation. There are no moving parts to break or wear out, and materials of construction resist corrosion.
The transmitter is available with HoneywellTM or HART® smart protocols or two-wire Analog 4-20mA output, and is intrinsically safe when used with an approved
power supply. World Wide Hazard Certifications are available.
