Business services is a general term that describes work that supports a business but does not produce a tangible commodity. Information technology (IT) is an important business service that supports many other business services such as procurement, shipping and finance.
A mass airflow sensor. A mass (air) flow sensor (MAF) is used to find out the mass flowrate of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density as it expands and contracts with temperature and pressure.
GENERAL INFORMATION/EQUIPMENT DESIGN. In a mass flow hopper, all the material inside the hopper moves down the walls and exits. The flow is based upon a first-in, first-out principle and is uniform and reliable upon discharge. Moisture content, temperature, age, oil content, and solid levels must be regulated to ensure effective flow.
