The meter is maintenance-free and has a long lifetime which guarantees minimum yearly operating costs. MULTICAL® 402 is used for heat, cooling and combined heat /cool-ing measurement in all water-based systems with temperatures from 2 to 160°C. The meter has been developed for measurement of energy consump-tion in family and multiple occupancy housing, housing associations, blocks of flats and small industry. FunctionalityMULTICAL® 402 consists of calcula-tor, flow sensor and two temperature sensors and is simple to install, read and verify. Our flow sensor range for MULTICAL® 402 comprises of the sizes 0.6 – 15 m³/h, and the supply options are 230 or 24 VAC mains module, 2xAA-cell battery, or D-cell battery with up to 16 years’ lifetime. MULTICAL® 402 is fitted with a connector for the supply and thus, it is easy to change battery or mains supply.By means of the calculator’s two front keys it is easy to adjust date and time or reset operating hour counter and info-event counter. Furthermore, the keys can be used to display log data, incl. yearly or monthly logger.MULTICAL® 402 receives pulses from up to two connected hot or cold water meters and carries out remote accumulation of energy and volume via pulse outputs. If you change from pulse input to pulse output, the meter is automatically configured for pulse inputs and pulse outputs respectively – without manual reconfiguration. Wireless readingThe meter is remotely read via Wire-less M-Bus or radio module. Con-sumption data is read, saved and transferred by means of the USB Meter Reader. Furthermore, radio can be read by means of a hand-held terminal or form part of a Kamstrup radio network. The transferred data is used for individual billing, consumption analysis and/or energy optimisation.Compact meter for heat and cooling with maximum functionalityD A T A S H E E T ?

V is the supplied water volume?T is the temperature difference measured k is the thermal coefficient of water The calculator always calculates energy in [Wh], and then it is converted into the selected measur-ing unit.Application typesMULTICAL® 402 operates with four different energy formulas, E1...E9, that are all calculated in parallel in connection with each integration no matter how the meter is configured.The four energy types are calculated as follows:E1=V1(T1-T2)k Heat energy (V1 in flow or return)E3=V1(T2-T1)k Cooling energy (V1 in flow or return)E8=m³xT1 (Flow pipe)E9=m³xT2 (Return pipe)This renders MULTICAL® 402 capable of calculating the heat and cooling energy of most applica-tions, both closed and open systems.All energy types are data logged and can be displayed in-dependent of configuration.Flow measurementMULTICAL® 402 calculates current water flow every 12 seconds or every 4 seconds depending on configuration.Power measurementMULTICAL® 402 calculates current power on the basis of current water flow and the temperature difference measured in connection with the latest integration.Current power is updated in the display every 24 seconds or every 4 seconds depending on configuration. Calculator functions35810725_E1_GB_11.2010MULTICAL® 402D A T A S H E E TE [Wh] = V x ?T x k x 1000E [kWh] = E [Wh] / 1,000E [MWh] = E [Wh] / 1,000,000E [GJ] = E [Wh] / 277,780E [Gcal] = E [Wh] / 1,163,100The upper push button is used to switch between the primary readings. The consumers typically use the first primary readings in connection with self-reading for bill-ing purposes.The lower push button is used to show secondary informa-tion on the selected primary reading.Min. and max. flow and powerMULTICAL® 402 registers minimum and maximum flow and power on a monthly as well as on a yearly basis. The registrations which can be read via data communication include max. and min. flow and power values, all with date indication.All max. and min. values are calculated as largest and smallest aver-age respectively of a number of current flow or power measurements. The average period used for all calculations is selected in the interval 1…1440 min.Temperature measurementMULTICAL® 402 is available in different versions for either Pt100 or Pt500 sensors in a 2-wire version.The measuring circuit includes a high resolution analog/ digital converter with a temperature range of 0,00°C…165,00°C.In addition to current temperatures for the energy calculation average temperatures on a yearly and monthly basis can also be displayed.Display functionsMULTICAL® 402 is equipped with a clear LC display including 8 digits, units of measurement and infor-mation panel. In connection with energy and volume readings 7 digits and the units of measurement to match are used, whereas 8 digits are used when e.g. meter number is read.As a starting point the display shows accumulated energy. When the push buttons are activated the display reacts immediately by calling other readings. The display automatically returns to accumulated energy reading 4 minutes after the latest activation of the push buttons.Calculator functions4 5810725_E1_GB_11.2010MULTICAL® 402D A T A S H E E TInfo code Description Response time0 No irrigularities -1 Supply voltage has been cut off -4 T2 sensor outside range, short-circuited or cut off < 30 sec.8 T1 sensor outside range, short-circuited or cut off < 30 sec.4096 District heating leak < 30 sec.16384 District heating burst < 30 sec.
