Purpose of the development: The flow meter VRTK-2000 (hereinafter VRTK-2000) designed to measure the volume and flow of electrically conductive liquids (water, milk, alcohol aqueous solutions) in the filled pressure lines for technological purposes and commercial registration, including heat meters.

Recommended application field: Utilities.

Technical characteristic: Specifications: VRTK-2000 measures and displays the liquid crystal display (LCD), the following parameters: • accumulated m3 and flow rate, m3 / h In addition, in 2000 VRTK a mode display overhead, which indicates: • serial number of the device; • the price of the output pulse; • power supply voltage; • The temperature of the liquid (VRTK-2000-K), or the flow rate of conformity. current of 20 mA (VRTK-2000-B); • the value of the additional LSB (used for verification). Performed VRTK-2000-B provides a standard current output 4 ... 20 mA, powered by an external power supply voltage of 18 ... 24 V. Operating temperature range of the liquid - 20 ... 150 ° C. Dining VRTK-2000 (PPS) is a lithium battery with a voltage of 3.65 V with a lifetime of at least 5 years since the release of the device manufacturer. PI-1 has its own power supply - a lithium battery with a voltage of 3.65 V with a lifetime of at least 5 years since the release of the device manufacturer. Outside the main relative error of measurement of VRTK-2000 - 0.5%, 1%, depending on the model in the range from minimum to maximum flow. Outside the main relative error of flow VRTK-2000 - 1% in the range from minimum to maximum flow. The limits of the main relative error of converting the amount of fluid in the number of output pulses VRTK-2000, CDA + 0.5%, 1%, depending on the version in the range from minimal to maximal costs. Outside the main relative error of converting a current signal flow with + 1.5%.

Advantages over analogues: Features: Energy independence and metrological stability indisputable advantages of these devices. The new design allows dampened the main drawback, the fear of sediment (mud). Reliability indicators: • Average life, years, not less than ................................ 10 • The average time to failure, hr, min .................... 50,000 VRTK-2000 (PPS) have degree of protection IP65, GOST 14254, climatic design UHL 3 according to IEC 15150. In terms of resistance to climatic influences relate to the execution group C3 by GOST 12997 and designed to operate in ambient temperatures from -10 to + 50 ° C and relative humidity STI lower than 95%. In terms of resistance to mechanical stress VRTK-2000 (PPS) are vibration-resistant and-vibroproch Nome execution of N1 to GOST 12997. VRTK-2000 (PPS) are resistant to the external magnetic field strength up to 400 A / m, varying sinusoidally with a frequency of 50 Hz, suitable for operating pressures up to 1.6 MPa.

The development stage readiness: Introduced in production

Technical and economic effect: Volatile, a lithium battery with a life of at least 5 years.

Description of the development:
()
The flow meter VRTK-2000 consist of: flowmeters CDF (the CDF); transducers measuring PI (the PI). CDF can be used as a part of VRTK-2000, and separately for use in the other means of measurements (the heat, etc.). VRTK-2000 is available in two versions: - VRTK-2000-R (compact), the CDF and the PI are made with a single body. - VRTK-2000-B (with remote UI, separate), the CDF and the PI-1 (Remote UI) tavlivayutsya manufactured in separate housings and connected two-wire connection up to 100 m To connect various devices in VRTK-2000 (PPS) provides a pulse output with pulse value, established at the request of the customer.
