Non-pressure hybrid flow meter-counter Volga Triton
The Volga Triton pressure-free hybrid flow meter is designed to measure the volumetric flow of liquid in water ducts with a pressure-free and combined pressure-free flow mode. The submerged primary speed converter operates on the basis of the Doppler effect, emitting an ultrasonic signal towards the flow and receiving an echo reflected from particles in the flow with a frequency different from the frequency of the emitted signal. This frequency shift is called the "Doppler Shift" and it is proportional to the flow rate. A non-contact ultrasonic primary converter VBN-DG-01 or any other third-party liquid level converter with a unified current output of 4-20 mA can be used as a depth meter: radar, hydrostatic or ultrasonic.
The volumetric flow rate is determined both by the "area-speed" method and by MI2220-2013, depending on hydraulic conditions.
In non-contact (radar) mode, the Volga Triton flowmeter is designed to measure the volumetric flow rate of a liquid in a non-pressurized flow mode. The flow meter can be used as part of waste water metering units in non-pressure (gravity) sewage systems, open irrigation and reclamation channels, open or underground derivational non-pressure water pipelines of hydropower facilities, diverting supply and recirculation water pipelines of thermal power and other hydraulic structures with a non-pressure flow regime. The measurement technology is based on a non-contact radar method for measuring surface flow velocity and a non-contact ultrasonic/radar method for measuring water level.
As a water level meter, both the proprietary ultrasonic level sensor BP-G-01 and third-party sensors connected via unified digital or analog interfaces, for example, VEGAPLUS, can be used.
The pressure-free hybrid flow meter "Volga Triton" became the winner of the International Environmental Award EWA Award 2021 in the nomination Best technology.
