The ultrasonic Oriole flow meter is designed to measure the volumetric flow rate and volume of liquid in pressure pipelines. The measured medium can be any homogeneous isotropic liquid of various densities, including: clean cold and hot water supply and heating systems (up to +160 °C); natural water is clean and of a low degree of pollution; wastewater of low and medium degree of contamination; chemical solutions of acids, alkalis and other chemically aggressive media; mineral, synthetic and semi-synthetic machine oils; food products (vegetable oil, juices, syrups, vodka, ketchups, dairy products, etc.). Secondary converter It is available in both stationary (~220 V) and portable versions with autonomous power supply. Primary converters Mortise, contactless overhead outside and full-bore primary converters embedded in the process allow you to place the measurement gate on any water pipe made of any material, taking into account design features. Pipe sizes Du, mm: 25, 32, 40, 50, 65, 80, 100, 150, 200, 250, 300, 350, 400, 500, 600, 700, 800, 900, 1000, 1200, 1400, 1600, up to 6000 mm

Issued according to specifications 20.59.52-003-51284861 -2017 They are used as reference solutions for transmitting the pH scale of aqueous solutions during calibration and adjustment of pH meters of the 2nd-class accuracy and below, by direct measurement.

The water treatment system (hereinafter referred to as the system) is used for the preparation of water used in hydrogen generators, for the preparation of solutions, chromatographic samples, capillary electrophoresis, high-performance liquid chromatography (HPLC), etc. analyzers requiring the use of high purity water. The system is connected directly to the municipal water supply line and allows obtaining high–purity deionized water with a specific electrical conductivity of 0.06 - 0.1 mcm/cm. The device uses multi-stage water purification. Technical specifications System output capacity, l/h not less than 6 Specific electrical conductivity of water, mcm/cm not more than 0.06 – 0.1 Power supply - single-phase AC 220V, 50/60 Hz Maximum power consumption, kW 0.1 Dimensions (W x D x H), mm 200 x 560 x 440 Weight, not more than 20 kg

Water purification in the device is carried out by passing it through a composition of deionization resins and sorbents. Resins and sorbents are located in filter elements placed in a replaceable cassette. The distilled water to be cleaned is poured into the feed tank, the filler neck of which is placed on the upper plane of the device and hermetically sealed with a screw cap. Technical specifications: The specific conductivity of the resulting water, not more than, mkSxcm 0.20 Capacity, at least, l/h 6 Operating time of the replaceable cassette (total volume of purified water), not less than 700 liters Volume of refilled distilled water, l. 1 Power consumption, not more than, VA 20 Overall dimensions (width×depth×height), mm 180×450×380

The flow meter is fully developed by Russian specialists in the field of acoustics, hydraulics and electronics, and is designed to measure the volumetric flow rate and volume of water in pipelines, mainly medium and large, under pressure, non-pressure and combined (pressure-free) flow modes. The flowmeter is based on ultrasonic "time-pulse" multipath technology for measuring the flow velocity in the measuring range. In addition, depth sensors (primary transducers) - hydrostatic, radar contactless, ultrasonic underwater or ultrasonic contactless - are used to measure the flow in water ducts with a combined or non-pressure flow mode. In the presence of deposits affecting the shape and area of the live section of the flow, sediment level sensors are used. Secondary converter It is available in both stationary (~220 V) and portable versions with autonomous power supply. Primary converters Inset and overhead primary converters from the inside allow you to place the measurement gate on any water pipe made of any material, taking into account design features. Pipe sizes Du, mm: 200, 250, 300, 350, 400, 500, 600, 700, 800, 900, 1000, 1200, 1400, 1600, up to 15000 mm The Volga ML acoustic ultrasonic flowmeter is registered as a type of measuring instrument in the Federal Information Fund for Ensuring the Uniformity of Measurements for No. 78414-20 (MP 2550-0361-2019). The Volga ML acoustic ultrasonic flow meter has been recognized as the winner in the nomination Best Technology of the International Environmental Award EWA Award 2020.
