Battery-powered laser level sensors from BinMaster (Lincoln, NE) make it simple to mount and power level sensors on bins and silos without the complexity or expense of wiring. The patent-pending single point laser installs quickly through a 1.5” NPT connection on silos or in remote locations where inventory monitoring has not been feasible. Powered by replaceable Lithium batteries, the SPL-200 measures solids in silos up to 98 feet tall in low or no-dust environments. The FVL-200 measures livestock feed in bins up to 35 feet tall. Both models take interval readings from once per hour to once a day with a battery life of three to five years.
