Doppler flowmeter operates on the principle of the Doppler Effect, which is a change in the observed frequency of a wave (sound wave /light wave) due to relative motion between the wave source and the object. These flow meters use reflected ultrasonic sound to measure fluid velocity of slurries, aerated liquids or liquid with bubbles, and gases with sound-reflecting particles, where other meter don’t work.
The Doppler flowmeter can be easily installed outside the pipes which will not have any influence on pressure loss in the pipe, and has been gaining increasing demand for key beneficial factors such as low power consumption, corrosion resistant, and ability to obstruct less flow. They are ideal for wastewater applications or any dirty liquid which is conductive or water-based as well as for applications where chemical compatibility, low pressure drop and low maintenance are required.

Doppler Flowmeter Market – Dynamics
Doppler Flowmeter Market to Grow with Rising Demand for Wastewater Treatment
Sales of Doppler flowmeters remain driven by its non-intrusive design that allows flow measurements at high precision and high frequency. Doppler flowmeters find applications in treatment of contaminated water and other liquids containing dirt particles and slurries which usually cause damage to conventional devices like sensors. A notable rise in the use of such flow meters in wastewater treatment plants, sewer networks, pump stations, hydropower plants, and in special constructions of the wastewater sector such as storm water overflow tanks, for measuring flow rates and fluid velocity will continue to drive the growth of Doppler flowmeter market.
Sales of Laser Doppler Flowmeters to Pick Pace
Laser Doppler flowmeters are gaining wide application in monitoring the rate of blood flow through skins and other organs, complemented by their non-invasive design. Rapid expansion of healthcare industry lined with an increase in the adoption of new devices and technologies will augur well with the growth Doppler flowmeter market.
Rising application of Doppler flowmeters in the flow measurements of influent and effluent water, crude oil, digester feed control, acids, mining slurries, liquefied gases will further augment the market expansion. However, the Doppler flow measurements lack accuracy on clear portable liquids or pure water, which may pose as potential threat to the growth of Doppler flowmeter market.
