  • Page 5: Introduction

    INTRODUCTION The Preso COIN® flow meter accommodates most flows, even the most abrasive . Accuracy and reliability are achieved by its rugged construction, practical design and simple principle of operation . It stands alone in its ability to maintain the necessary square root relationship between flow rate and differential pressure for almost any type of flow .
  • Page 6: Straight Pipe Run Requirements

    Straight Pipe Run Requirements STRAIGHT PIPE RUN REQUIREMENTS Proper operation and performance is dependent on the required lengths of unrestricted upstream and downstream piping . The minimum length of the upstream side of the COIN Flow Element depends on the type of fitting at the start of the straight run, and the pipe configuration .
  • Page 7: Selecting A Mounting Location

    Selecting a Mounting Location SELECTING A MOUNTING LOCATION Install COIN elements horizontally, rotated 90° along the pipe center line, see Figure 2 . This method of mounting allows for free passage of solids and eliminates air entrapment at the transmitter connection . Other positions are acceptable provided there is proper venting of the transmitter and differences in lead line elevations are considered .

  • Page 10 Selecting a Mounting Location Figure 9: Typical vertical installation for steam NEVER EXCEED THE MAXIMUM PRESSURE OR TEMPERATURE RECOMMENDED FOR THE MEASURED PROCESS. EXCEEDING PROPER PRESSURE OR TEMPERATURE RATINGS CAN LEAD TO PERSONAL INJURY OR EQUIPMENT DAMAGE. THE PROCESS PIPING FLANGES SHOULD BE IDENTICAL TO THOSE ON THE COIN METER. THE PROCESS TEMPERATURE AND PRESSURE SHOULD NEVER EXCEED THAT FOR WHICH THE ELEMENT WAS DESIGNED.

    The high pressure connection is always on the upstream side of the flow direction arrow and the Iow pressure connection on the downstream side . Fittings used must be able to withstand the process temperature and pressure conditions as well as provide proper corrosion resistance . Badger Meter offers three types of fittings, see “Typical Pressure Port Configurations” on page 12 .
