Abstract

Foreliggende oppfinnelse angår et system for fjernovervåkning av nivået til et flytende medium i minst én tank. I henhold til oppfinnelsen er hver tank utstyrt med en nivåsensor (1) tilkoplet en styreenhet (3). Styreenheten innbefatter en transiderenhet for kommunikasjon med en sentral enhet og er tilpasset å kommunisere med den sentrale enheten ved angitte tidspunkter og å levere et alarmsignal dersom væskenivået i tanken faller under en spesifisert verdi. Systemet gjør det også mulig å installere driftsparametrene til styreenheten, slik som dens identitet og de forannevnte angitte tidspunkter, fra den sentrale enheten.The present invention relates to a system for remote monitoring of the level of a liquid medium in at least one tank. According to the invention, each tank is equipped with a level sensor (1) connected to a control unit (3). The control unit includes a transducer unit for communication with a central unit and is adapted to communicate with the central unit at specified times and to deliver an alarm signal if the liquid level in the tank falls below a specified value. The system also makes it possible to install the operating parameters of the control unit, such as its identity and the aforementioned specified times, from the central unit.
