PRESSURE OR AIRFLOW SENSORS? - Honeywell

At the simplest level, an airflow sensor, or more precisely a mass air flow sensor, is a device with two pressure ports where gas flows from one port to the other (see Figure 1). Inside the sensor, there’s a sense element with a heated surface. As gas flows across the sense element, heat is transferred from upstream to downstream, as shown in Figure 2. This creates a thermal imbalance ...

· Time out – This is the duration after which the sensor task attempt will fail. By default, this value is set to 7 days. IMPORTANT – How does poke interval, retry and timeout work out? Something which is not apparent from the airflow documentation, unless you actually go thru the code. So here is an example, this is applicable to all the sensors irrespective of the type. Let’s say we have ...

What is the Active Flow Timeout in Flow sensors ...

· This is where the active flow timeout setting of xFlow sensors in PRTG plays its important role. The Active Flow Timeout setting makes PRTG delay data processing for the respective xFlow sensor by the value you set for the active flow timeout. With this approach, PRTG can record the received volume as close as possible to the time it is delivered. For example, if an xFlow sensor in …

Thermal Mass Flow Sensors for Gas and Liquid Applications

non-corrosive gases (, air, nitrogen, helium, argon, oxygen, etc.) to prevent them from degradation and avoid irreversible damage. There are some exceptions with sensors employing protective layers, such as silicon carbide, to protect them from harsh environments. These sensors can be used for corrosive media, such as gasoline and diesel. Thermal mass flow sensors are used in a growing ...

Hot Film Mass 5 (HFM5) Air Flow Sensors - Autologic

As air flows over the measuring sensor, the uniform temperature profile at the sensor changes. On the inlet side, temperature drops faster since the air flowing past this area cools it off. On the opposite side of the sensor, the temperature drops slightly, because the incoming air has been heated by the heater element. The change in temperature distribution leads to a temperature difference ...

MASS AIR FLOW SENSOR (MAF) - Autoditex

Disadvantage of the volume air flow sensor is that it measures the volume of the incoming air. Therefore, it is necessary to calculate the amount of fuel to determine the mass of air and thus to adjust the sensor readings in accordance with the air density. Solution to this problem is placing an additional temperature sensor along with the air volume sensor. Output signal of MAF, made by BOSCH ...
