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. Secondary converter It is available in both stationary (~220 V) and portable versions with autonomous power supply. Primary converters VBN-DS-01 Primary speed converter for medium and large water pipelines VBN-DS-02 Combined primary speed and depth converter for medium and small aqueducts VBN-DS-03 is a combined low-profile primary speed and depth converter for small aqueducts.

Rubidium frequency standards H1-1022 are available both in the standard version and with various options that have differences in functionality and technical characteristics: option 01 is a device with high short–term stability of the output signal frequency; option 02 – a device with a low-level phase noise in the output signal spectrum; option 03 – the device has a binding module in its composition, which allows automatic correction of the frequency of the output signal according to the signal of the external time scale; option 04 – the device has a synthesizer module in its composition, which allows you to receive a sinusoidal signal of a given frequency at the output of the device in the range from 100 Hz to 100 MHz in steps of the order of 4 × 10-6 Hz; option 05 is a device with an extended range of ambient operating temperatures. Through the built-in RS-232 interface, telemetry information is collected from the device nodes, and commands to change the frequency of the output signal are transmitted. The H1-1022 frequency standards have no domestic analogues in terms of their small dimensions, weight, power consumption and operating time, as well as in terms of their numerous functional capabilities.
