Purpose of the development: Water Meter LV-4T is designed to measure the volume of water consumed, while controlling the quality of its heating.

Recommended application field: Utilities.

Technical characteristic: Specifications: - Stand-alone power supply, battery life - 6 years; - permissible deviations of water meter accuracy in the measurement of: in the upper range of Qt - Qmax ± 2%; in the lower measuring range Qmin - Qt ± 5%; - The limit of absolute error in the measurement hot water temperature of ± 5 ° C; calculator calculates the amount of hot water flowing and records computing the value in the appropriate cell of the cumulative tariff, based on the actual water temperature - 40 ° C, the service is not taken into account; - 40 ° C to 44 ° C is taken into account 70% of services; - 45 ° C to 49 ° C is taken into account 90% of services; - 50 ° C and above 100% of services is taken into account.

The development stage readiness: Introduced in production

Technical and economic effect: In the course of the study researches found that the difference between the cost of acquisition, calibration, installation of mechanical counters and counter LV-4T, given the results of the above calculations, is 620 USD.

Description of the development:
()
Feature of the billing meter is consumed amount of hot water depending on its temperature, according to "Rules of the provision of services for water-, heat supply and sanitation." The kit consists of an electronic calculator LP, a digital temperature sensor DT05; two converters Flow - PWG to be installed on hot water piping and RMP to be installed on cold water pipes. For the calculation of charges for water services must be received at the end of the billing period to take readings from the tariff of cells "Vhv" (the amount of cold water), "Vgv" (the amount of hot water) and "Vsgv" (corrected obm hot water) were counted by the volume of water in the cells "Vhv" and "Vgv" calculation is carried out for the amount of water consumed without heating it (as in cold), and for water heating charges are held in a cell were counted in the volume "Vsgv", which is already used all the relevant factors. . The device implements the task of remote wireless transmission of measured data, which is incorporated as an additional feature to its main purpose.
