With the continuous development of flow sensors, more and more types of flow sensors are gradually coming out, and they have their own advantages and disadvantages, flow sensors.
1. Advantages
(1) The flow sensor can be used to measure industrial conductive liquids or slurries.
(2) No pressure loss.
(3) The measurement range is large, and the diameter of the electromagnetic flow transmitter is from 2.5mm to 2.6m.
(4) The flow sensor measures the volumetric flow rate of the measured fluid under the working state, and the measurement principle does not involve the influence of the temperature, pressure, density and viscosity of the fluid.
2. Defects
(1) The application of the flow sensor has certain limitations, it can only measure the liquid flow of conductive media, but cannot measure the flow of non-conductive media, such as gas, alcohol and other non-conductive liquids
(2) When the flow sensor is used to measure the viscous liquid with dirt, the viscous or precipitate adheres to the inner wall of the measuring tube or the electrode, which changes the output potential of the transmitter and brings the measurement error, and the dust and scale on the electrode reach a certain thickness, which may lead to the appearance being unable to measure.

Load cell range and accuracy – ifm
1. Sensor scale:
1) Normal use (static experiment or quasi-static experiment, when the frequency of application is not high, the scale of the sensor should be selected to consider the measured force value, as well as the component of the auxiliary tool (test fixture), etc.).
2) When used dynamically, the scale of the sensor is generally larger than the ...

Differential pressure sensor function – ifm sensors
A differential pressure sensor is a sensor used to measure the difference between two pressures, usually used to measure the pressure difference between the front and rear ends of a device or component.
A typical application of differential pressure sensors is to measure the difference in exhaust pressure between the front and rear channels of the exhaust particulate trap of a passenger car engine.

ifm wireless sensor analysis
1. After the wireless sensor device is installed, it appears to be beating or the number is inaccurate
Reason: There is electromagnetic interference on the site, or the signal line and the power line go to the same trunking.
Solution: The product function selected by the customer does not meet the on-site working conditions, and it needs to be installed or replaced.
