HI 7871 and HI 7873 mini level controllers are ideal for liquid level control over distances of up to 100 meters (330 feet). They are highly compact and will fit into tight spaces. These easy-to-use controllers are ideal for nearly any liquid level application, such as industrial and municipal water treatment, nutrient tank control in farming, hydroponics, aquacultural applications and plating rinse baths. HI 7871 features high and low level control, while HI 7873 includes an overflow alarm. Both instruments can be connected to a 2-wire transmitter, which is ideal for level monitoring in remote applications. A complete liquid level measuring system requires: 1) A controller (HI 7871 or HI 7873) 2) A bar holder with amplifier circuitry (HI 7874) 3) A package of measuring bars (HI 731324) 4) An undecal connector (HI 7164) HI 7871 requires 3 bars, one each for low and high levels and the third as a consent sensor. HI 7873 requires four bars with the additional bar used for overflow measurement.
