HRH Level Controllers monitor fluid level in wells, tanks, pools and reservoirs.
HRH level controllers can be used to monitor up to two tanks with single
point switching (empty or full tank), or to monitor one tank for two levels.It
works by means of two sensors,which measure resistance of fluid. For measuring
signal is used intermittent voltage 5V/50Hz. Using the alternating signal
increased oxidation of sensors is prevented , polarization and electrolysis
of fluid.
By DIP switch could be control two independent levels or use combined
function for monitoring of one level. Relay is equipped by regulation
of sensitivity to changing resistance of fluid. By setting sensitivity
according to real condition it is possible eliminate misreadings (e.g.pollution
of sensors, grounds, humidity etc.). For every sensor can be set up a
delay in range 0.5-10s and by DIP switch the type of delay (at switch
on and off relay, choice is made according to application requirement).
