Transit-Time Ultrasonic Flow Meter

An ultrasonic flow meter is a device commonly used to calculate volumetric flow of fluid.  There are two leading types, the transit-time and Doppler style meter.
In the transit-time ultrasonic flow meter,
the transducers are upstream and downstream of each other,
and each act as a transmitter and receiver.
One transducer, of course, emits the ultrasound signal with the flow, while the other emits it against the flow.
The meter measures the difference in transit time between the two transducers,
and the velocity difference is used to calculate flow.
Additionally, the introduction of a multi-path transit-time meter,
allows the meter to measure flow at more than one location,
which increases the accuracy of the meter and permits measurement in demanding flows
(swirls, irregularities and cross-flow).

Mediumno impurities, no corrosive gases, natural gas, etc.
The turbine flowmeter is considered one of the main traditional flow meter technologies,
along with differential pressure and positive displacement meters. They still are a favorite device used to measure gas flow, particularly for clean,
medium-to-high steady flow of low-viscosity fluids.
The turbine meter measures volumetric flow based on fluid flowing passed a free-spinning rotor,
with each revolution agreeing with a specific volume of fluid.
Turbine meters are used for measurement of liquids as well natural gas flow.

How is natural gas flow measured?

International natural gas trade measurement is divided into:
volume measurement, mass measurement and energy measurement.
There are many methods for natural gas flow measurement, and there are many available flow meters. According to the working principle, they are roughly divided into the following three types:
1) Differential pressure flowmeter:
In the current pipeline natural gas metering,
more than 95% still use the standard orifice differential pressure flowmeter,
indirectly measuring the parameters of natural gas pressure, differential pressure and temperature,
flowing through the standard orifice plate,
according to experience The formula calculates the volumetric flow of natural gas.
2) Volumetric flowmeter:
The display value of the volumetric flowmeter is generally the volumetric flow rate under working conditions.
It is manually calculated according to the standard state,
and the temperature and pressure values ​​are long-term average or estimated value.
3) Speed ​​flowmeter:
It is a flowmeter that directly measures the flow velocity of a full pipe in a closed pipe.
Including turbine flowmeter, vortex flowmeter, spiral vortex flowmeter, ultrasonic flowmeter, etc.
Since the measured flow rate is under working conditions,
the volume flow rate under the working condition is also shown last.
Intelligent spiral vortex flowmeters that use computers to automatically compensate for temperature and pressure in real time have also appeared on the market.
