Description
Multi-jet water meters are very accurate in small sizes and are commonly used between ½” to 2″ sizes for domestic, residential and small light industrial users. The water flow meters have several flow ports surrounding an internal chamber to create multiple jets of water against an impeller whose rotational speed depends on the velocity of the water flow. Multi-jets are very accurate at low flow rates.
Multi-jet meters include an internal strainer element that prevent the jet ports from getting clogged. These Multi-jet flow meters have an epoxy coated bronze alloy body, with internal measuring components made from modern thermoplastic materials and stainless steel, all tested for compatibility with potable water requirements. These WRAS approved multi-jet flow meters are an ideal flow meter for BMS system integration, sub-tenant metering and facilities monitoring.
