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

An Ultrasonic Flowmeter can be a kind of flow meter that measures the flow of a liquid, gas or steam by utilizing 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 among the pulses of ultrasound propagating into and against the direction in the flow. Ultrasonic Flowmeters are affected by the pressure, temperature, density and viscosity on the flowing medium.

You can find three distinctive kinds of Ultrasonic flow meters.

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

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

Multivariable In-line Flowmeters, are utilized for Volumetric or mass flow monitoring of most liquids, gases or steam. Multivariable In-line Vortex flowmeters utilizes 3 primary sensing elements, a vortex shedding velocity sensor, a temperature sensor, and also a pressure sensor to measure the mass flow rate of liquids, gases or steam.

In-line Vortex flowmeters operates within a following manner:

   * It measure flow of liquids, gas and steam by detecting the frequency at which vortices are alternatively shed from a bluff physique.
   * As flow passes a bluff physique within the flow stream, vortex meter, the vortices build low and high pressure zones behind the bluff body, or shedder bar.
   * In-line liquid flowmeters uses a piezoelectric crystal sensor to detect the pressure exerted by the vortices on the velocity sensor.
   * The piezoelectric crystal converts these "pulses" into electrical signals. The meter utilizes a sensor created to make a robust sensor and to decrease potential leaks.

In-line Flowmeters are classified into the following models:

  1. Pro-V? Model M22-VTP
  two. Pro-V? Model M22-VT
  3. Pro-V? Model M22-V
  4. Pro-V? Model M22-EM
  five. Pro-V Model M22-R

The Model M22-VTP presents you flow pc functionality in a compact field device.

The Model M22-VT integrates a precision 1000 Ohm platinum RTD temperature sensor that may be used to calculate and output compressed mass reading.

The Model M22-V delivers direct reading of volumetric flow rate-generally one of the most cost-effective remedy for liquid flow monitoring-in applications ranging from common water flows to hydrocarbon fuel in flow measurement.

The Model M22 Energy Monitoring option permits real-time calculations of power consumption to get a facility or procedure. The meter is often programmed to measure steam, hot water or chilled water.

The Model M22-Redundant flowmeter provides dual flowmeters inside the exact same pipe spool for vital flow applications or exactly where a backup technique is needed.

VorTek Instruments LLC. manufactures precision multivariable gas mass flow meters including In-line Flowmeters and Insertion Flowmeters for the measurement of liquid, gas, and steam in commercial, industrial applications.
