Residential Ultrasonic Meters
ZENNER Stealth Ultrasonic Residential Meters (Model ZSUR) featuring advanced all-digital ultrasonic technology with no moving parts for optimal revenue protection and long-term performance. Solid-state sound measuring technology ensures precise measurement without compromised performance over time. 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 0.03 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. Lead-free bronze tube construction. Submersible design exceeds IP68 standards and can be installed in any position. Battery life up to 12 years with easy user replacement. Complies with AWWA C715 and C750 standards.
