Vortex flowmeter series instrument because of the use of the environment or harsh in the field work sometimes present such and such problems, resulting in production will be affected, vortex flowmeter and orifice flowmeter and V-cone flowmeter are different, as far as the orifice flowmeter is concerned, it is a high-range ratio differential pressure flow device composed of a standardized orifice plate and a multi-parameter differential pressure transmitter (or differential pressure transmitter, temperature transmitter and pressure transmitter), which can measure the flow rate of gas, steam, liquid and induction, and is widely used in petroleum, chemical industry, metallurgy, electric power, Process control and measurement in the fields of heating and water supply. The vortex flowmeter is mainly used for the flow measurement of industrial pipeline medium fluids, such as gas, liquid, vapor and other media. It is characterized by small pressure loss, large measuring range, high precision, and is not affected by fluid density, pressure, temperature, viscosity and other parameters when measuring the volume flow under working conditions. There are no moving mechanical parts, so the reliability is high and the amount of protection is small.
How to prevent the problem of elliptical gear flowmeter is as follows:
The scale of an elliptical gear flowmeter is the scale of flow used in a specific reference medium, such as liquid, which generally refers to water at room temperature. When used with other media, the available flow rate will vary depending on the viscosity and density of the medium. Since the oil flow specification device selects diesel oil with a viscosity greater than water and a density smaller than water as the calibration medium, the lower limit flow rate of the flowmeter will generally be increased accordingly to narrow the available flow scale. Therefore, it is normal for the vortex flowmeter to show a small flow rate function deterioration when calibrated on the oil flow calibration device. It is not difficult to deduce that if liquefied petroleum gas (LPG) is used to calibrate the vortex flow juice, the opposite result will be better than water.

Range, accuracy and installation of load cells – ifm
1. The scale of the sensor:
(1) In normal use (static test or quasi-static test, the frequency of use is not high), the scale of the sensor should be selected to consider the force value of the measurement, but also consider the weight of the auxiliary tool (test fixture) and so on.

Structural classification of UV sensors
1. Spherical cathode structure:
In order to fully avoid the tip effect and make the photoelectron emission more stable and uniform, it is necessary to fix the operating area on the cathode, because the ultraviolet tube relies on photoelectron emission and gas multiplication to complete the conversion of the optical signal into an electrical signal and amplify it.

How ifm inductive sensors work
How an inductive sensor works: An inductive sensor consists of three parts: an oscillator, a switching circuit, and an amplified output circuit. The oscillator produces an alternating magnetic field. When a metal target approaches this magnetic field and reaches the sensing distance, eddy currents are generated within the metal target, resulting in ...
