DTPR Tank PPr

DTPR Tank PPr transmitter in the SKES-2027B fuel system

DTPR Tank PPr is a lever-float fuel transmitter used in the SKES-2027B electric fuel quantity measuring system. This version is installed in the right external fuel tank of Mi-8 / Mi-17 / Mi-171 family helicopters. The transmitter sends the fuel level signal from the tank to the cockpit indication circuit. In English documents, this item should be described as a fuel transmitter, because it transmits tank level data to the fuel quantity indicator.

Fuel level measurement through Tank PPr

The transmitter uses a float and lever mechanism. When the kerosene level in the right external tank changes, the float moves and changes the electrical signal in the measuring circuit. After the crew selects the required tank through the P8U selector, the BE-09K indicator shows the corresponding fuel quantity. The transmitter does not measure fuel consumption and does not control fuel feed. Its role is limited to level indication inside the SKES-2027B system.

Refuelling signal from DTPR Tank PPr

The Tank PPr version is linked with the refuelling signal for the right external tank. When the fuel reaches the specified filling level, the transmitter circuit can activate the “tank full” indication used during ground refuelling. For Tank PPr, the refuelling signal point is 973 l. This value belongs to the right external tank position, so Tank PPr should not be replaced by Tank R, Tank Pl or Tank D without checking the aircraft documentation.

DTPR Tank PPr with BE-09K and P8U

The transmitter works in the same measuring chain as the BE-09K cockpit indicator, the P8U tank selector and the other DTPR transmitters in the SKES-2027B set. Tank PPr corresponds to the right external tank. Tank R is used for the service tank, Tank Pl for the left external tank and Tank D for the additional tank. If the displayed fuel quantity is incorrect, the fault may be in the transmitter, selector, indicator, wiring, grounding or adjustment circuit.

Identification and ordering of DTPR Tank PPr

Before ordering, the tank position must be confirmed. Tank PPr means right external tank. A transmitter from another tank position may look similar, but the lever geometry, electrical setting and refuelling signal point may differ. For correct selection, provide the helicopter type, installed fuel quantity system, tank position, transmitter marking and, if possible, a photo of the item or passport entry. The product is also known under alternative designations DTPR Tank PPr, SKES-2027B Tank PPr fuel transmitter and ДТПР Бак Ппр.
