TURBOCHARGER GP 6N8458 - Caterpillar

The 6V7925 Fuel Rate Indicator is an accurate fuel system diagnostic tool designed to measure engine fuel consumption. The indicator can be used in place of the 5P2150 Engine Horsepower Meter, and must be used with the 5P2148 Flowmeter (part of the 5P2149 Attachment Group).The 6V7925 Fuel Rate Indicator measures flow rates between 3 gallons per hour and 80 gallons per hour. Horsepower calculation and rpm measurement circuitry are not included in the fuel rate indicator. For rpm measurements, use the 6V3131 Multitach Group. Features
ADAPTABILITY: The indicator can measure fuel flow rates on all Caterpillar 1100, 3200, 3300 and 3400 series engines, and 6 1/4 bore "V" engines.HOUSING: A rugged, break-resistant plastic case protects the instrument from damage.GPH READOUT: Gallons per hour (gph) are directly displayed on a liquid crystal four digit display in numbers .5 inches high. The display is visible in direct sunlight and low light conditions.INPUT: Connection is provided for the 5P2157 Flowmeter Cable from the 5P2148 Flowmeter.POWER: Power for the indicator is supplied by an internal 9 Volt battery.AUTOMATIC SHUTOFF: A battery saver circuit automatically turns off the indicator when there is no input signal (less than approximately 3 gph).LOW BATTERY LIGHT: A red lamp glows on the front of the indicator when it is time to change the battery. If this lamp is on, the indicated flow may not be correct.PORTABILITY: The fuel rate indicator is a lightweight, hand-held instrument; an improvement over the more cumbersome 5P2150 Engine Horsepower Meter.CALIBRATION: A 6V3030 Multimeter (or equivalent) and a 1.5 Volt flashlight battery are used for easy bench calibration of the indicator.RELIABILITY: The 6V7925 Fuel Rate Indicator with the new 8T5118 Circuit Board has been designed and tested to withstand severe environmental factors such as high humidity, extreme temperatures, etc.Specifications
POWER: An internal 9 Volt battery (alkaline), type NEDA 1604A, is used to provide power for the fuel rate indicator.BATTERY LIFE: Approximately 20 hours of continuous operation.MEASUREMENT RANGE: 3.0 to 80 gallons per hour.ACCURACY: 6V7925 Indicator - .1 gph typical ( .2 gph max) in specified measurement and operating temperature range.6V7925 Indicator and 5P2148 Flowmeter - .5% of reading plus .1 gph (Example: At 20 gph, .5% = .1gph; plus .1 gph = .2 gph accuracy).READOUT UPDATE RATE: Approximately once per second.INPUT: Directly compatible with 5P2148 Flowmeter.CALIBRATION FACTOR: ... 1.250 Volts dc = 40.0 gph (31.25 mV = 1 gph).OPERATING TEMPERATURE RANGE: ... 32°F to 140°F(0°C to 60°C)STORAGE TEMPERATURE RANGE: ... +14°F to +140°F(-10°C to +90°C) with battery removed.SIZE: ... 7.5 in.(190 mm) x ... 4.4 in.(112 mm) x ... 1.6 in.(40 mm).WEIGHT: ... 1 lb(.45 kg)Components Of The 6V7925 Fuel Rate Indicator
