ZENNER Stealth Ultrasonic Meters (Models ZSU Cast Iron Housing and ZSUS Stainless Steel Housing) engineered for commercial and industrial applications with large diameter capability from 2" through 12". Advanced all-digital ultrasonic technology with no moving parts ensures optimal revenue protection and long-term performance. Solid-state sound measuring technology provides precise measurement without performance degradation. Designed for high accuracy with dynamic flow range across potable and non-potable clean water applications. Bidirectional flow measurement capability with minimal head loss reduces pressure complaints and pumping costs. Ultra-precise leak registration with low flow sensitivity as low as 0.12 GPM. LCD display shows total volume and additional information including flow rate, direction, battery life, and leak alarms. Sampling rate of 4 times per second ensures accurate flow change detection. Submersible design exceeds IP68 standards and can be installed in any position. Battery life up to 12 years. ZSU features cast iron housing for standard applications; ZSUS features stainless steel housing for corrosive environments.
