Introduction
ZENNER Ultrasonic Residential Meters are designed for applications requiring high accuracy, long life, and a dynamic flow range. The highly advanced, all-digital technology achieves precise measurement without any moving parts, ensuring optimum revenue without compromised performance over time. These meters are used for the measurement of both potable and non-potable clean water in commercial and industrial settings and are capable of bi-directional flow measurement. The meter design has minimal head loss, decreasing pressure complaints from customers and reducing pumping costs for the utility.
Operation
ZENNER Ultrasonic Residential Meters use solid-state, sound measuring technology to measure instantaneous flow and calculate cumulative flow volume. The LCD display has two rows. The first row shows total volume, which is factory programmed for US Gallons, Cubic Feet, or Cubic Meters. The second row displays additional information such as rate of flow, flow direction, remaining battery life, leak alarms, and empty pipe alerts. These meters are capable of ultra-precise leak registration with low-flow sensitivity as low as 1/32 GPM.
Construction
ZENNER Ultrasonic Residential Meters consist of three basic components: the tube, the electronics & display package, and two transducers. The tube is available in either lead-free bronze or stainless steel.
Communication
ZENNER Ultrasonic Residential Meters have a universal communication protocol package capable of producing outputs compatible for use with Encoded, Pulse, or 4-20mA systems. These meters are designed to be connected to any existing AMR/AMI system.
Maintenance
ZENNER Ultrasonic Residential Meters are engineered and manufactured to provide long-term service and operate virtually maintenance-free. There are no moving parts to service. The battery pack has a standard life-time of up to 12 years and is designed for easy user replacement. It does not require a return to a ZENNER facility for replacement.
Conformance
ZENNER Ultrasonic Residential Meters are tested and comply with ANSI/AWWA Standard C750-10.
Installation
ZENNER Ultrasonic Residential Meters are designed to fit the same laying length as most standard multi-jet and positive displacement meters. With no moving parts to damage, these meters can be used safely and accurately with or without a strainer. These meters are submersible and exceed IP68 standards. These meters can be installed in any position, including horizontal and vertical, with flow in the up direction.
Connections
These meters have been designed with ease of installation in mind through the use of built-in wrench pads on meter sizes 5/8" through 1". Tailpiece/Unions for installations of meters are available as an option for various pipe types, sizes, and misaligned pipes.
