Ultrasonic flow meter is a general term used to describe measurement devices for velocity or flow . However, an ultrasonic flow meter is a device which will either measure the flow velocity , volume or mass flow of a liquid or a gas.
The ultrasonic flow meters are now manufactured in all sorts of types and applications ranging from transit time clean fluid applications or Doppler based flow meters for dirty fluids or hybrids which do both. .
EESIFLO International is an ISO 9001/OHSAS 18001 certified manufacturer and a division of the EES Group of Companies with more than 22 years of providing service to every industry including the oil and gas, petrochemical and water/waste water related industries. Non intrusive methods of measuring flow have become popular in certain applications because of the convenience of not having to cut a pipe, stop a process or contaminate surrounding areas with toxic chemicals.EESIFLO has been involved in simple measurements of water to more complex measurements of oil or even mixtures of both in extreme conditions. We manufacture high quality, high performance measurement devices for general industry applications and also for oil and gas applications . More>>

Sierra Instruments: Innova-Sonic® Model 205 ultrasonic liquid flow meter
Innova-Sonic® Model 205 ultrasonic liquid flow meter is a state-of-the-art universal transit time ultrasonic liquid flow meter incorporating the latest developments in digital signal processing. Sophisticated ultrasonic sensor technology coupled with powerful transducers deliver highly accurate flow measurements for liquids in full pipes. While principally designed for measuring clean liquid applications, the device is tolerant of liquids with a small quantity of air bubbles or suspended solids common in most industrial applications.
The Model 205 offers low power consumption, high reliability, and outstanding applicability at an economical price. This ultrasonic measure features an easy to read display and clear, user-friendly menu selections make using the instrument simple and convenient. This ultrasonic flow meter can be configured via keypad without any additional programming device, is packaged in a die cast NEMA 4X (IP65) housing, and like the Innova-Sonic™ Portable Model 210, is available in your choice of non-invasive clamp-on or insertion transducer configurations.

Ultrasonic Flowmeter
PRINCIPLE OF OPERATION
Most commonly people will distinguish this technology into two types of measurement technique An ultrasonic flow meter will be categorized into either a Doppler type (which uses the Doppler shift principle) or a transit time device which apparently measures the Delta T or time of flight path. These distinctions have probably been brought about because of the need for simple classifications of ultrasonic flowmeters in the industry. However hybrid ultrasonic flow meters exist which can use both techniques.
Nowadays we can see manufacturers using combinations of both the transit time and the phase shift information and in combination with other ultrasound technologies . Ultrasonic Meters can be insert or clamp on types for general industry applications or the explosion proof type meter.
ULTRASONIC FLOW METER SELECTION
There are many types of ultrasonic flow meters using single or multiple variations on a technology for all types of liquids, gas and even steam.
Transit Time Meter Basic Theory
Measurements
are made by sending bursts of signals through a pipe
. The measurement of flow is based on the principle
that sound waves travelling in the direction of flow
of the fluid require less time than when travelling
in the opposite direction.
Doppler Flowmeter Basic Theory
Doppler ultrasonic flowmeters operate on the Doppler shift principal , whereby the transmitted frequency is altered linearly by being reflected from particles and bubbles in the fluid.
