Ref Silicon Chip November 2007 Looking for a water tank level meter that's easy to install, accurate and doesn't need a complicated in-tank sensor? This PIC-based unit uses a pressure sensor to monitor water level and display tank level via an RGB LED at the press of a button. The kit can be expanded to include an optional wireless remote display panel that can monitor up to ten separate tanks (KC-5461) or you can add a wireless remote controlled mains power switch (KC-5462) to control remote water pumps. Basic tank monitor kit includes electronic components, case, solder mask and screen printed PCB and pressure sensor. Some fitting may be required to suit your particular tank.
