Where is the Mercedes-Benz Viano air flowmeter installed?

The installation position of Mercedes-Benz Viano air flowmeter is as follows:

(1) Between the air cleaner circuit and the throttle body.

(2) It can be installed on the air filter.

(3) The air flow meter and throttle body can also be integrally installed on the engine.

Note: According to the different measuring principles, there are vane type, Carmen spiral type and thermal type air flow meters.

When the air flow meter is used, the airflow pushes the turbine blades to rotate through the flow meter. The number of revolutions of the impeller is proportional to the volume of gas passing through the air flow meter. A specially designed patent guide frame is installed at the entrance of the flowmeter, which accelerates the airflow entering the flowmeter with the increase of flow velocity.

Extended data

Application field:

1. Flow measurement is a science that studies the quantitative change of substances, and the law of mutual change of mass is the basic law of the development of things, so its measurement object is not limited to pipeline liquid in the traditional sense, and there are problems in flow measurement wherever quantitative change is needed.

2. Flow, pressure, weight and temperature are listed as three main testing parameters. For a certain fluid, as long as these three parameters are known, its energy can be calculated, and these three parameters must be detected in the measurement of energy conversion. Energy conversion is the basis of all production processes and scientific experiments, so flow, pressure and temperature instruments are widely used.
