3.1 Rev Features. Horizon. Materials and Specifications. Horizontal Turbine Meters Sizes 1-1/2", 2"

Transcription

1 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 horizontal turbine meter is built to maintain accuracy over extended periods of use. CONFORMANC TO STANDARDS: turbine meters have some of the widest flow ranges of any turbine meters on the market. All series turbine meters meet or exceed the latest performance and accuracy standards of AWWA C71. Two inch meters have FM Approval. Maximum continuous flow rates may be exceeded by as much as 5% for intermittent periods. CONSTRUCTION: The 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 is designed to allow quick, easy, in-line exchange of the measuring element without removing the maincase from the installation. Interchangeability of many parts within various sizes minimizes spare parts inventory and the comes standard with built-in strainer. RGISTR: 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 totalizing register has a straight-reading odometer type display; 3º 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.) OPRATION: 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 Thrust design extends the life of the meter by dividing wear between two points: during low flow the 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 rotor floats between both tungsten carbide bearings with sapphire bushings providing radial support for the rotor. STRAINR & TST PORT: Standard Built-in Strainer.

Designed for applications where accuracy is an essential part of maintaining revenue. The horizontal turbine meter is built to maintain accuracy over extended periods of use. CONFORMANC TO STANDARDS: turbine meters have some of the widest flow ranges of any turbine meters on the market. All series turbine meters meet or exceed the latest performance and accuracy standards of AWWA C71. meters in sizes 3"-1" are FM Approved. Maximum continuous flow rates may be exceeded by as much as 5% for intermittent periods. CONSTRUCTION: The 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 is designed to allow quick, easy, in-line exchange of the measuring element without removing the maincase from the installation. Interchangeability of many parts within various sizes minimizes spare parts inventory. Built - in test ports are standard for ease of field testing.
