The HP PROTECTUS® III Stainless Steel (S) fire service meter has become the industry standard and is designed for applications where fire service and drinking water supplies are fed by a single line. The HP PROTECTUS III S measures extremely wide flow ranges at 98.5%-101.5% accuracy, registering leaks or unauthorized use of water from fire service lines. The design of the HP PROTECTUS III S combines low-flow sensitivity of disc meters with high-flow capacity of turbine meters for an extremely wide flow range. All HP PROTECTUS III S fire service meters are NSF/ANSI 61 certified, Annex F and Annex G compliant, meet or exceed AWWA C703 Standards, and are Underwriters Laboratory (UL) Listed and Factory Mutual (FM) approved for fire service use.
HP PROTECTUS III S is designed to measure both domestic and fire service water usage through a single water line. A typical application would be in a warehouse, hotel, or hospital where one water line may supply any number of faucets or bathrooms as well as an automatic sprinkler system.
The HP PROTECTUS IIII S is the next industry standard for fire service meters by combining all of the features of the HP PROTECTUS III S with a new 300 series stainless steel body.
