Flow meter

The anti-explosion protection class II 2G Exdb IIB/IIC T* Gb, ATEX indicates that the flowmeter is suitable for use in areas where there is a risk of explosion due to gases (Zone 1, for example). This classification means the device is designed to prevent ignition of surrounding explosive atmospheres and is constructed to a high […]

Modbus and ProfiNET represent different stages of development of industrial communications, each with its own advantages and disadvantages. Modbus is simple and easy to use, suitable for small systems; ProfiNET is efficient and stable, suitable for large and complex networks. Converting Modbus to ProfiNET can improve system performance and scalability. In actual scenarios, the production

1. The orifice flowmeter should be equipped with a section of measuring tube during installation. At least one 10DN and a second 5DN straight pipe section should be maintained to improve measurement accuracy. 2. If valves need to be installed before and after the orifice flowmeter, it is best to choose a gate valve and

Serial Communication refers to a communication method that transmits data through a serial port. Data is transmitted bit by bit through data signal lines, ground wires, etc. Common serial ports include RS-232, RS-485 and RS-422. It should be noted that the serial port is only an interface standard. It specifies the electrical standard of the

Electromagnetic flowmeters, turbine flowmeters and vortex flowmeters are all commonly used flowmeters. They each have their own characteristics and usage environments. The following is their comparison: 1. Electromagnetic flowmeter: no mechanical moving parts, stable and accurate measurement, simple maintenance, but cannot measure non-conductive liquids Wide application range and large flow rate range Can measure liquids

The unstable output signal of the vortex flowmeter may be due to the following reasons: 1. Changes in the mass or pressure of the fluid: This may cause deviations in the measurement results of the flow meter. 2. Improper installation position: As mentioned above, if there is not a long enough straight pipe section or

Some common problems with instrument power supplies include unstable power supply, overheating of the power supply, too high or too low current, damaged power lines, etc. Here are some solutions to these problems: 1. The power supply is unstable: First check whether the power line is loose or damaged. You can also try to replace

An important feature of modern chemical production is the large-scale and highly automated production equipment. Automation is the basic condition and important guarantee for the safe operation, smooth operation and improvement of efficiency of production equipment. However, with the development of production and the improvement of automatic control level, the corrosion problem of chemical instruments

Several situations in which the measured liquid may cause malfunctions to the electromagnetic flowmeter may include: Poor liquid conductivity: The working principle of the electromagnetic flowmeter is to measure flow based on the conductivity of the liquid. If the conductivity of the liquid being measured is low, normal measurement may not be possible or the

Electromagnetic flowmeter is a flow measurement device designed based on Faraday’s law of electromagnetic induction. When using and debugging electromagnetic flowmeters, you can follow the following tips: 1. Perform zero point calibration: Zero-calibrate the electromagnetic flowmeter when the fluid in the flowmeter is stationary. This ensures accuracy during future use. 2. Pay attention to the
