Abstract:
PCT No. PCT/SE86/00570 Sec. 371 Date Jul. 23, 1987 Sec. 102(e) Date Jul. 23, 1987 PCT Filed Dec. 12, 1986 PCT Pub. No. WO87/03667 PCT Pub. Date Jun. 18, 1987.The present invention concerns a method of sensing and indicating errors in a dosing circuit, in which a pumping device (1) pumps a fluid via a conduit system out to at least one dosing device (3) located nearby a dosing place. The dosing device (3) measures and discharges intermittently a predetermined volume of the fluid through a pressure controlled non-return valve (16) to the dosing place, when the pressure in the conduit system is increased from a low pressure to a high pressure during a certain limited time. The invention is characterized in that an error in the dosing circuit is sensed and indicated by measuring the pressure in the dosing chamber (11) and the time from a chosen reference time during a dosing cycle, that a checking is made continuously or intermittently that a combination of simultaneously measured valves of pressure and time is kept within predetermined limits for such a combination, an error being sensed and a signal being emitted when the combination of the measured values is not kept within such limits.
