"~__ @ HORIZON Em i es Z Features APPLICATIONS: For use in the measurement of potable water for applications where flow is consistently moderate to high. Designed for applications where accuracy is an essential part of maintaining revenue. The Horizon horizontal turbine meter is built to maintain accuracy over extended periods of use. CONFORMANCE TO STANDARDS: Horizon turbine meters have some of the widest flow ranges of any turbine meters on the market. All Horizon series turbine meters meet or exceed the latest performance and accuracy standards of AWWA C701. Maximum continuous flow rates may be exceeded by as much as 25% for intermittent periods. CONSTRUCTION: The Horizon consists of three basic parts: maincase; measuring insert: and register. Maincases are made of bronze. Measuring elements are thermoplastic with unique inlet and outlet straightening vanes. To simplify maintenance, the Horizon is designed to allow quick, easy, in-line exchange of the measuring element without remov- ing the maincase from the installation. Interchangeability of many parts within various sizes minimizes spare parts inventory and the Horizon comes standard with built-in strainer. REGISTER: Permanently sealed register has a unique seal and heat-treated glass to eliminate dirt, moisture infiltration and lens fogging. An integral tamper-proof locking feature is provided to prevent tampering of the register and calibration vane. The total- izing register has a straight-reading odometer type display: 3600 test circle with center sweep hand and a low flow (leak) detector. Standard gearing is used, making registers interchangeable by size. All Hersey Meter models have electronic meter reading systems available for increased reading efficiency (see Meter Reading Systems.) OPERATION: Water flows straight through the measuring element where it turns a rotor at a rate in direct proportion to the quantity of water flowing through the meter. The straight-through design allows high volumes to flow with a minimum of head loss. Retro ThrustO design extends the life of the meter by dividing wear between two points: during low flowthe tungsten carbide bearing in the rotor floats against a stainless steel shaft; during high flow a second tungsten carbide bearing gently moves back against another stainless steel shaft. During medium flow, the rotorfloats between both tungsten carbide bearings with sapphire bushings providing radial support for the rotor. STRAINER & TEST PORT: Standard Built-in Strainer. Test port is optional with spool piece. CONNECTIONS: ANSI Class 150 Flanges. 1 -1/2' NPT pipe threads on optional test outlet.
