- In detail
It is intended for use in the opened and closed system of heat supply, as two independent counters of liquid, the batcher, in systems of regulation of thermal energy. TECHNICAL CHARACTERISTICS Diameter of a flow-mesuring site … …. from 10 mm to 3000 mm. Range of measurement of an expense … (0,2¸100). Limits of the allowed errors: at measurement of temperature ±0,1ºС; at measurement of an expense, volume and mass of liquid δv = ± (1+0,01 Qmax/Q), but no more than ± 5% at measurement of thermal power and thermal energy in the range of expenses of 0,4¸100% for a difference of temperatures of Dt: dE = ± (2+4dtn/Dt+0,01 Qmax/Q), consumption Power: from the Hz network 220B, 50. no more than 2,5 VA; from a source of a direct current of 12 V no more than 2,0 W. All available to the user of information it is brought to the two-lower case liquid crystal indicator. The choice of the displayed parameters is made by one button. The non-volatile archive of values of expenses of liquid (heat carrier), thermal energy and temperatures, has volume for storage of hourly average values for 85 days and average daily values for 2,5 years. Malfunctions in work are defined automatically, are given for the indicator and are fixed in archive together with emergence time, duration and type of malfunction.
