An ultrasonic water meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow. Using ultrasonic transducers, 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 or by measuring the frequency shift from the Doppler effect. Ultrasonic flow meters are affected by the acoustic properties of the fluid and can be impacted by temperature, density, viscosity, and suspended particulates depending on the exact flow meter. They vary greatly in purchase price but are often inexpensive to use and maintain because they do not use moving parts, unlike mechanical flow meters.
How do ultrasonic meters work?
Ultrasonic Water Meter ensures pinpoint accuracy and reliability throughout the entire lifetime. Built without any moving parts, the meter allows for completely flexible mounting and offers extremely low start flows, secured hygiene as well as no loss of accuracy over time. For over 30 years, ultrasonic meters have had unrelenting precision whether they are installed in the cold of Iceland or the heat of the Middle East. ;
How to Use Ultrasonic Irrigation Water Meter
Ultrasonic Irrigation Water Meters are commonly applied to measure the velocity of liquids that allow ultrasonic waves to pass, such as water, molten sulfur, cryogenic liquids, and chemicals. Transit time designs are also available to measure gas and vapor flow. Be careful because fluids that do not pass ultrasonic energy, such as many types of slurry, limit the penetration of ultrasonic waves into the fluid. In Doppler ultrasonic flowmeters, opaque fluids can limit ultrasonic wave penetration too near the pipe wall, which can degrade accuracy and/or cause the flowmeter to fail to measure. Transit time ultrasonic flowmeters can fail to operate when an opaque fluid weakens the ultrasonic wave to such an extent that the wave does not reach the receiver.
Industries Where Used
The industries in order of higher to lower are oil and gas, water and wastewater, power, chemical, food and beverage, pharmaceutical, metals and mining, and pulp and paper.
Application Cautions for Ultrasonic Flowmeters
For transit time ultrasonic flowmeters, be sure that the fluid can adequately conduct ultrasonic waves, because the flowmeter will not measure when the ultrasonic waves cannot penetrate the flow stream between the transducers. Similarly, ultrasonic waves must be able to penetrate the fluid for Doppler flowmeters to operate accurately. When the fluid is relatively opaque and does not penetrate the fluid, Doppler flowmeters tend to measure the velocity of the fluid at or near the pipe wall, which can cause significant measurement error and/or cause the flowmeter to fail.
Avoid fluids that can coat wetted transducers or coat the pipe wall in front of non-wetted transducers because the flowmeter will not measure when the ultrasonic waves cannot enter the flow stream. Be sure to maintain reliable clamp-on transducer connections to the pipe wall because the flowmeter will not measure when the ultrasonic waves are not able to reach the fluid.
ULTRASONIC BULK WATER METER ;
The ultrasonic bulk water meter is for use in drinking water distribution and industrial applications. The ultrasonic bulk water meter is used to record high and fluctuating flows in drinking water distribution and in industry, with a very low-pressure loss at the same time.
A bulk meter is a large meter that we fit pipes to help us find leaks. They are usually fitted to pipes that supply large blocks of flats and they’re only used to measure water flow and will not affect your bill.
Ultrasonic Water Meter(Bulk Water Meters) is an innovative flow meter with a static flow sensor based on the ultrasonic measuring principle. Ultrasonic Water Meter utilizes ultrasonic measuring methodology and microprocessor technology. All calculation and flow measuring circuits are designed on one single board, thus offering exceptional accuracy and reliability.
