Ultrasonic Flowmeters
A Flowmeters is a device for determining, monitoring, or tape-recording the rate of flow, pressure, or discharge of a liquid, since a gas.
An Ultrasonic Flowmeter is a type of flow meter that determines the flow of a liquid, gas or steam by utilizing the principle of ultrasound. The flow meter can measure the average speed along the course of a produced beam of ultrasound, by averaging the difference in measured transit time in between the pulses of ultrasound propagating into and against the direction of the flow. Ultrasonic Flowmeters are affected by the pressure, temperature level, density and viscosity of the flowing medium.
There are three various kinds of Ultrasonic flow meters.
Transmission flowmeters, which can be distinguished into In-line flowmeters and Non-Intrusive flowmeters.
Reflection or Doppler flow meters.
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 utilized for Volumetric or mass flow monitoring of the majority of liquids, gases or steam. Multivariable In-line Vortex flowmeters uses 3 main sensing components, a vortex shedding speed sensor, a temperature sensing unit, and a pressure sensing unit to determine the mass flow rate of liquids, gases or steam.
In-line Vortex flowmeters operates in a following way:
It determine flow of liquids, gas and steam by detecting the frequency at which vortices are alternatively shed from a bluff body.
As flow passes a bluff body in the flow stream, vortex meter, the vortices develop high and low pressure zones behind the bluff body, or shedder bar.
In-line Flowmeters uses a piezoelectric crystal sensing unit to discover the pressure put in by the vortices on the speed sensing unit.
The piezoelectric crystal transforms these "pulses" into electrical signals. The meter uses a sensing unit created to create a robust sensor and to decrease prospective leakages.
In-line Flowmeters are categorized into the following designs:
Pro-V Design M22-VTP
Pro-V Design M22-VT
Pro-V Design M22-V
Pro-V Model M22-EM
Pro-V Model M22-R
The Design M22-VTP provides you flow computer system functionality in a compact field gadget.
The Design M22-VT integrates an accuracy 1000 Ohm platinum RTD temperature sensing unit that can be utilized to compute and output compressed mass reading.
The Model M22-V provides direct reading of volumetric flow rate-generally the most affordable option for liquid flow monitoring-in applications varying from general water streams to hydrocarbon fuel in flow measurement.
The Design M22 Energy Monitoring choice permits real-time estimations of energy consumption for a facility or process. The meter can be set to measure steam, hot water or chilled water.
The Design M22-Redundant flowmeter offers dual flowmeters within the very same pipe spindle for crucial flow applications or where a backup system is needed.
