High Flow Combination Meters

Sizes 4” through 12” & Custom models on special order USA Patents

Our strainers exceed all fire service requirements.

OPERATION:[nbsp]
Water initially flows through a large Fire Flow Strainer with open strainer area equal to 10 times the pipe inlet diameter. Performance High Flow Combination Meters utilize a turbine type meter on the main flow line, a turbine type meter on the intermediate line and a proportionately sized meter on the low flow line. There are three Check Valves, one each on the high, intermediate and low flow lines that control the flow of water through the appropriate measuring devices. Before the intermediate and high flow check valves open, all water flows through a low flow meter. As flow demand increases the intermediate and high flow check valves progressively open, and water can flow through all three meters.

CONSTRUCTION:
ZENNER PERFORMANCE High Flow Combination Meters consist of a Fire Flow Strainer, two Class II Turbine Meters (PMT), one PMN Nitro I Multi-Jet Meter on the low flow line, three check valves and bypass shutoff valves on the intermediate and low flow lines. All steel and cast iron components are epoxy coated.

COMPLIANCE:
ZENNER PERFORMANCE High Flow Combination Meters are tested and comply with ANSI/AWWA C702, C703 and ISO performance standards.
