Compact Heat Meter SENSOSTAR®2

Application flexibility: ■ flow sensors in single-jet or coaxial multi-jet versions (qp 0.6, 1.5 or 2.5 m3/h). ■ available for all common measuring point types (standard, ista®1 or Allmess®2 measuring points). ■ temperature sensors with various diameters (5.0, 5.2 and 6 mm) and connection cable lengths (1.5 m or 3.0 m). ■ rotatable and, in the separable version SENSOSTAR®2+, an easily detachable calculator. ■ Simple operability and read-out using the straightforward menus and the large and clearly laid out liquid crystal display. ■ 15 monthly values can be read out over the display and 18 monthly values over the optical interface. ■ Exact measurements because of very low flow threshold values (e.g. 2.5 l/h for the coaxial multi-jet flow sensor in the nominal size qp 0.6 m3/h). ■ Reliable measurements guaranteed by routine calculator self-checks ■ The battery has a guaranteed lifetime of 6+1 years. ■ A battery with a lifetime of 10 years is available as an option. ■ Available as options: an M-bus interface or a potential- free contact for volume or energy. ■ Available in Europe with an MID conformity declaration, meaning that a country- specific verification is not necessary.

Calculator SENSOSTAR®2C

■ Calculator for combined heat meters (optionally for cooling meters or heat/cooling meters) ■ Protection class IP65 ■ Large, easy-to-read display ■ Constant display of the total energy consumed ■ 3-in-1 mounting system for direct screw mounting, Engelmann wall-mounting support or mounting (DIN) rail ■ For Pt500 temperature sensor pairs ■ Automatic detection of 2-wire or 4-wire technique ■ Temperature measurement range from 1° to 180°C ■ Infrared interface with daylight filter Optional interfaces: ■ M-bus with power supply or ■ Two pulse outputs for volume and energy ■ Connection of up to two additional meters possible via the pulse input interfaces ■ Convenient operating and configuration software ■ No loss of data at change of battery because of EEPROM memory ■ Battery easy to exchange (Engelmann replacements only) without damaging verification seals ■ Optional power supply via additional power pack ■ Approval heat for heat ■ German national approval for cooling In the development of the SENSOSTAR®2C calculator the experience of over 30 years of pro-ducing heat meters has been united with the customer wishes of today and tomorrow. The result is a calculator that convinces through its measurement accuracy, long lifetime and robustness. In particular, the generous dimensions of the terminal box allow for simple connection of the connecting cables. The high-strength cable glands with strain relief for up to 6 cables protect against humidity and dirt. The housing cover has two convenient snap-open positions (at 80° and 140°), which allow easy and comfortable direct mounting of the SENSOSTAR®2C, and connection of cables.

Electronic water meter WaterStar

■ For cold or hot water ■ Fits 2˝ EAS metering points ■ Flat and compact design ■ Low flow threshold values: leakage caused by dripping faucets or defective flushing are rec-ognized ■ Large and easy-to-read display (can be rotated 360° for optimal positioning) ■ In addition to the standard display of the amount of water consumed, statistics and mainte-nance data can be read via the display ■ Storage of the data in a non-volatile memory is standard, no additional module necessary ■ Simple data transmission to a PC via infrared interface and Engelmann® Monitor software ■ WATERSTAR is standardly equipped with a battery with a 10-year lifetime. ■ MID approval ■ Three optional additional interfaces can be added at the factory (state when ordering): ■ M-bus ■ M-bus (with power supply) or ■ pulse output
