Ultrasonic Flowmeters

 A Flowmeters is a device for measuring, monitoring, or recording the rate of flow, pressure, or discharge of a liquid, as of a gas.

An Ultrasonic Flowmeter is a type of flow meter that measures the flow of a liquid, gas, or steam by using the principle of ultrasound. The flow meter can measure the average velocity along the path of an emitted beam of ultrasound, by averaging the difference in measured transit time between the pulses of ultrasound propagating into and against the direction of the flow. Ultrasonic Flowmeters are affected by the pressure, temperature, density, and viscosity of the flowing medium.

There are three different types of Ultrasonic flow meters.

  1. Transmission flowmeters, which can be distinguished into In-line flowmeters and Non-Intrusive flowmeters.
  2. Reflection or Doppler flow meters.
  3. Open-Channel flowmeter.

Ultrasonic Flowmeters such as In-line Flowmeters are Multivariable Flowmeters as it is used for the measurement of liquid, gas, or steam in industrial applications for the water and wastewater treatment plant, chemical and petrochemical, oil and gas, power, pharmaceutical, paper, food, and beverage industries.

Multivariable In-line Flowmeters are used for Volumetric or mass flow monitoring of most liquids, gases, or steam. Multivariable In-line Vortex flowmeters utilize three primary sensing elements, a vortex shedding velocity sensor, a temperature sensor, and a pressure sensor to measure the mass flow rate of liquids, gases, or steam.

An Optimized Ultrasonic Cleaner Will Improve Your Cleaning Experience!

 To understand how an ultrasonic cleaner works and how it may do sonification or cleaning, one must first grasp the fundamentals of ultrasound and how it is used in ultrasonic cleaning. The transmission of sound at frequencies above the human hearing range is known as ultrasound. Ultrasound energy causes cavitation, the technical part of ultrasonic cleaning, which is generated at 40,000 times per second by piezoelectric electrical devices. Because the energy is focused at a tiny size, it is safe for parts despite its strength. It is possible to lessen liquid surface tension by adding a surfactant or wetting agent to the bath. The reduction in surface tension improves cavitation strength. The activity of ultrasonography is greatly aided by a medium evaporation. Low evaporation rate causes cavitation bubbles to explode with greater force, however this results in a higher cavitation threshold and fewer bubbles. High pressure of the liquid is ineffective; it produces more bubb

Comparing Capacitive and Eddy-Current Sensors

  Sensor Construction Understanding the difference between capacitive and eddy-current sensors begins by looking at how they are constructed. At the center of a capacitive probe is the sensing element. This piece of stainless steel generates the electric field which is used to sense the distance to the target. Separated from the sensing element by an insulating layer is the guard ring, also made of stainless steel. The guard ring surrounds the sensing element and focuses the electric field toward the target. All of these internal assemblies are surrounded by an insulating layer and encased in stainless steel housing. The housing is connected to the grounded shield of the cable. The primary functional piece of an eddy-curren t probe is the sensing coil. This is a coil of wire near the end of the probe. Alternating current is passed through the coil which creates an alternating magnetic field; this field is used to sense the distance to the target. The coil is encapsulated
