High- and Low-Water Alarms

Reliable water level monitoring is critical in commercial aquaculture facilities where unexpected high or low water conditions can result in equipment damage, stock loss, or system failure. Pentair AES High and Low Water Alarms provide immediate audible and visual alerts the moment water levels move outside acceptable ranges, giving operators time to respond before a situation becomes costly. Each unit operates via a mechanical float switch on a 15' cable, offering straightforward installation across a wide range of applications including aquaculture tanks, sumps, sewage systems, and septic tanks.

Two enclosure options are available to match your installation environment. The indoor Tank Alert is housed in a NEMA 1 metal enclosure and is well suited for climate-controlled rooms and hatchery buildings. The indoor/outdoor Tank Alert is housed in a Type 3R watertight thermoplastic enclosure, built to withstand exposure to moisture and varying temperatures in exterior or unconditioned installations. Both models feature a red warning light, audible horn, silence switch, and test button. High-water models trigger when rising water reaches the float; low-water "L" models are configured to alert when levels drop. All units run on 115V with a 6' power cord and carry UL and CSA approval. Backed by a three-year limited warranty.
