Type: turbine flow meter

Measuring range: 0.0018 ~ 0.072 ( m3 / h )

Precision grade: Grade A

Applicable medium: Diesel

Working pressure: 3 ( MPa )

Operating temperature: - 30 ~ 65 ( c )

One, overview:

Accurate fuel metering can reflect a car running and the engine combustion condition, and also reflect the oil quality and some other human and non-human factors resulting in increased fuel consumption.

Two, design:

According to the characteristics of vehicle running, the working environment and the current situation, especially the total shock and strong vibration conditions to reduce and eliminate error signal, we selected the flow velocity in the tangential turbine flow form. In materials, components and the size of the five generation design transformation. Are stereotyped as GN-B car type. GN-B type flowmeter in other industry applications, fully embodies the advantages: small volume, simple structure. As a pure mechanical part, it does not volumetric flowmeter with high accuracy. But with the development of electronic industry, its nonlinear through electronic compensation has been exceptionally high accuracy. The current can be compensated at 0.1% ml of equivalent coefficient of correction, so the type flowmeter metrology appraisal institutions of state authority is always 0.3%, the repeatability of 0.2%. This type of meter of high sensitivity, at engine idle state can correctly measure. Another characteristic is great power status under normal oil supply.

Fuel metering box is based on the current domestic situation of artificial oil stealing phenomenon to design a new generation of products.

Black box no display, actual oil consumption only through the 485 communication port access. Measurement to 0.1 ml for the units, 15 units, can measure 999.999 cubic. Communication can be informed of black box number, cumulative flow. Can also be zero and error correction value. Because the sensor orifice tiny, to artificially pumping, the first: to pump. Second: small flow rate, to draw a barrel of oil is often takes several hours. Black box recognized only after its flow value, truly reflect the actual engine fuel consumption.

As the new generation of automobile type fuel meter technical design requirements are as follows:

1, explosion proof

In 2, the material consists of 304 tensile stainless steel production.

In 3, leaving one times above the flow range of cases, using diamond ( ensure sensitivity ) and miniature bearing double rotating friction parts, in order to increase the service life and the consolidation of its stability, earthquake resistance.

In 4, GN-B Dan Lu, the models of history for a long time, it is directly mounted on the tank outlet, the precision can reach 0.3%.

Three, technical indicators:

Dielectric matter: 0 " diesel fuel metering unit: 0.1 ml

High pressure: 3Mpa metering: + 0.3%

Show show: 485 communication display sensor size: 35X35X55mm
