Adaptable Multi-point Fluid Level Sensor


Liquid systems all have their own specialty aspects and their own peculiarities.  The liquids vary in density and viscosity (flow level) in going from water with a centi-poise of 1 to liquid epoxies having up to 10,000 centi-poise.  Also, the temperatures can vary from -40°C for fluorinert (3-M liquids) to 200°C for pressure heated water and other special liquids.  Meeting these extremes is no easy matter.  Standex Electronics new LS04 series attacks these extremes along with multiple sensing points and multiple floats.  Therefore, liquid baths having two or more different liquids with different densities and viscosities can be simultaneously measured and their liquid levels monitored…
