Safety Procedures Be Prepared ! WARNING • Before using this product, read and understand the instructions. • All work must be performed by qualified personnel trained in the proper application, installation, and maintenance of equipment and/or systems in accordance with all applicable codes and ordinances.
Overview Differential Pressure (∆P) Transducer Overview The differential pressure (∆P) transducer is designed specifically for aviation fueling applications on jet fuel delivery vehicles, hydrant carts and stationary systems. The ∆P transducer It is compatible with Liquid Controls LectroCount LCR-II and LCR 600 electronic registers.
specifications and Dimensions Specifications Materials of Construction Body • Stainless steel (316L) Wetted Materials • Stainless steel (316L), Viton® seals Applicable Products • Class 2: Jet Fuel Pressure Rating Differential measurement range • 0 to 43.5 PSID (0 to 3 bar) for rated accuracy [60.0 PSID (4 bar) overpressure limit] Line pressure range • 0 to 150 PSI (0 to 10.
mechanical Installation Installation Overview 1. Install ΔP transducer and piping between a point immediately upstream and a point immediately downstream of the full flow fuel monitor or water coalescer. 2. Wire the ΔP transducer to the LectroCount electronic register. 3. Set the shutdown value on the LectroCount LCR-II or LCR 600. Mechanical Installation Installation Notes • The differential pressure transducer has two ¼"-18 NPT female ports.
Mechanical Installation Correct Orientations To install the ∆P Transducer: (cont.) 4. Mount the differential pressure transducer. Inlet and outlet fittings of the differential pressure transducer are ¼”-18 NPT, female threads. 4a. Position the differential pressure transducer in an upright orientation.
Electrical Installation Electrical Installation When ordered as part of a meter system with a LectroCount register, the ∆P transducer is wired to register at the factory. The ∆P transducer can also be ordered separately and installed onto a meter system already in service. Connecting the ∆P transducer to a LectroCount register requires the use of an additional board (PN 81944), which mounts directly to the LectroCount register’s circuit board.

Connect the four ∆P transducer wires to terminal block J3 on the LectroCount register CPU board and J16 on the 81944 board. • • • • • MH4 B J20 11 12 13 C2 POWER J6 9.
LectroCount Shutdown Value Setting Programming the ∆P Shutdown Setting Programming the ∆P Shutdown Setting on the LCRII: 1. Remove the switch plate from the selector switch. 2. Rotate the selector switch to the six o’clock position, the calibration mode. 3. Press the SELECT button until the display reads “dP XX.X”. XX.X represents the current differential pressure shutdown setting. 4. Press the INCREASE button to set the first (leftmost) digit to a number no greater than “5”. 5.
