Mass Air flow Sensor (MAF). The Mass Air Flow sensor (MAF) is one of the key components of an electronic fuel injection system in your car. It is installed between the air filter and the intake manifold of the engine. See the diagram. The mass air flow sensor measures the amount of ...
With my PicoScope I connected to pin 5 on the air mass sensor. Pin 5 is the output pin and with engine idling it should output around 1.9 volts DC. Then I got confused — I thought I may have picked the wrong pin number. I checked my wiring harness diagram again and sure enough —...
In order for air to be removed from the flowmeter sensor, the flow speed in the flowmeter sensor must be at least 1 m/s. If the fluid contains solid particles, especially in conjunction with too little flow, a level installation location of the flowmeter sensor and positioning of the input...
18.An apparatus for simulating an air intake of an internal combustion engine, comprising:a filter-housing for receiving an airflow;an in-line blower for drawing the airflow through an air filter;a throttle valve for regulating the airflow;a differential pressure sensor coupled with the filter-...
Check Installation: Verify that the flow meter is installed in the correct position and securely connected to power and communication interfaces. Ensure there are no obstacles around the flow meter. Measurement Point Setup: Inspect the sensor to ensure it is in good condition. ...
Indications of such are: Visible discolouration's or condensation on the viewing-glass of the transmitter, corrosion damages to the enclosure, 2.7.2 Coriolis mass flow sensor The sensor is largely maintenance-free. When handled correctly its functionality will only be impaired by corrosion...
The laminar flow bypass (often called LFE which stands for "laminar flow element") generates a pressure drop, P1–P2, forcing a small fraction of the total flow to pass through the sensor tube (m1). Figure 1-1. Flow Paths through the Instrument Two resistance temperature detector (RTD) ...
Theory of Operation The model FT4A is an innovative thermal gas mass flow meter and temperature transmitter. It is microprocessor-based and field programmable. The FT4A thermal sensor operates on the law that gases absorb heat. A heated sensor placed in an air or gas stream transfers heat in...
It is prohibited to use addi- tional, oversized or highly-deformable components or plumbing: (a) to control the mass distribution on the yacht; (b) to act as a yacht state sensor; (c) to store energy (except in permitted hydraulic accumulators); or (d) for any purpose other than ...
Figure 6. Diagram of the detection device: (a) Arrangement of test devices in vacuum cavities; (b) schematic diagram of the controlled flow of ethanol gas. The main parameters affecting the performance of the sensor are quality factor, frequency fluctuation, sensitivity, and resistance to enviro...
