Measuring equipment in the company TD Stroyservice
In the updated assortment of the company TD Stroyservice appeared metering devices for water and heat:
Features and benefits:
This is the standard of reliability for residential measuring devices, confidence in quality and durability. The stated warranty period for ITELMA water meters is six years, but the actual service life exceeds 10-15 years. Devices are resistant to pressure surges in the water supply system, which is extremely important in the operation of household appliances. They are not afraid of high temperatures. They have two installation options: vertical and horizontal, which saves space and time during installation. Convenient reading scale information, as well as the delivery of a pulse version, where the information is transmitted remotely. The device has a coarse filter, as well as a sealing wire, a meter passport, two gaskets and a pair of protective caps. ITELMA water meters have a high accuracy of metrological readings, and are equipped with anti-magnetic protection, have a high-quality brass body, good appearance.

Water meters METER
Features and advantages: the internal cross-section of the input and output pipes have an involute shape, a roller counting mechanism, a digital indicator device with the price of a lower discharge of 1 liter, multi-pole ring magnets in a magnetic coupling. Magnetic protection against external magnetic field. The maximum calibration interval. The chrome-plated brass body and design features of the water meter body exclude the possibility of leakage. The hinged lead seal eliminates the possibility of illegal manipulation of the device. Appearance to meet modern requirements, the set of connecting fittings is brass, the thread on the fitting is conical with a stop. The nut has "ears" for sealing all components of the water meter in contact with water are checked and allowed for use on drinking water

Heat meter HEAT METER WESER
"WESER HEAT METER" heat meters are designed to measure and register heat energy (amount of heat), the volume of the heat carrier and other parameters of the heat carrier in closed water heating systems. The heat meter is used as a means of commercial metering of heat energy in the apartments, individual residential buildings and other non-residential buildings, where the rated coolant flow does not exceed values for the corresponding size of the heat meter.
Technical parameters:
- Ambient temperature: +5 to +55°C
- Relative humidity: 30 to 80 %;
- Atmospheric pressure: from 84 to 106.7 kPa (from 630 to 800 mm Hg.)
- Flow meter temperature range: +9 to +90°C
- A set of temperature sensors — a matched pair of platinum thermoresistors with an ohmic resistance of 1000 Ohms (Pt 1000)
- Verification interval-4 years
- Warranty period: 5 years
