Differential pressure transducer Liquid Controls

The differential pressure transducer monitors the differential pressure (pressure drop) between a point immediately upstream and a point immediately downstream of the full flow fuel monitor, water coalescer, or other device typically applied in aviation fueling systems. The maximum differential pressure observed during the fuel delivery is electronically input into the LectroCount® LCR-II® Electronic Register.
The highest differential pressure reached during the delivery is printed on the
delivery ticket to provide a record of the maximum pressure drop. The corresponding flow rate at which this maximum differential pressure is observed is printed immediately after the differential pressure reading. This information appears on the delivery ticket in the form:
DP 12.4 PSI @ 242.6 GPM
In the aviation industry, a differential pressure of more than 25 PSID across the full flow fuel monitor is considered unacceptable according to ATA Specification 103. A differential pressure more than 15 PSID across a water coalescer is considered unacceptable. The differential pressure transducer has a maximum differential pressure of 60.0 PSID. Interlocks on the LCR-II electronic register, if employed, shut down fuel delivery if the differential pressure reaches or exceeds the programmed differential pressure shutdown value.
This system is designed for application on Jet Fuel delivery vehicles, hydrant carts, and stationary systems and is currently available for use with the Liquid Controls LectroCount® LCR-II® Electronic Register with SR214 operating software (version 4.04 or higher) and compatible ticket software.
