• Ultrasonic Flowmeters: From Principle to Application

  by artang hang November 4, 2025
  Ultrasonic flowmeters are based on the relationship between the propagation velocity of ultrasound and the flow velocity of the medium. They measure flow rate by measuring flow velocity. The following is an in-depth understanding of the working principles of ultrasonic flowmeters, including their pr...

• Selecting Flange Pressure Transmitters

  by artang hang November 4, 2025
  Flange pressure transmitters use capillaries instead of pressure guide tubes, so there is no need for insulation and heating; the temperature of the measured medium can be very high, and the temperature of Changhui Instrument's high-temperature pressure/differential pressure transmitter can reach ab...

• What types of electromagnetic flowmeters are there?

  by artang hang November 3, 2025
  Electromagnetic flowmeters are flow measurement instruments widely used in industrial automation and control. Based on their installation method and structural features, electromagnetic flowmeters can be divided into three types: insertion type, straight tube type, and split type. Insertion Type El...

• Situations Where Vortex Flowmeters Are Not Suitable

  Vortex flowmeters are commonly used flow measurement instruments, suitable for measuring the flow of a variety of liquids and gases. Their high accuracy, stability, and reliability have led to their widespread application in many fields. However, in practice, vortex flowmeters are not suitable for a...

• Differential Pressure Transmitter - Types and Applications

  by artang hang November 2, 2025
  A differential pressure transmitter is a device that measures the difference in pressure between the two ends of a transmitter. Unlike a general pressure transmitter, it has two input pressure ports, which are divided into a positive pressure port and a negative pressure port. Measurement can only b...
