  • Page 25: Instrumentation Of The Turbine Meter

    Instrumentation of the turbine meter Instrumentation of the turbine meter Connect the turbine meter to the Readout 3.1.1 Pickup coil ™ The pickup coil output is an electrical signal of varying amplitude. In most cases a Daniel pre-amplifier is mounted on the turbine meter to amplify this signal. A two conductor shielded cable is used to connect the pickup coil to the pre-amplifier, with the shield grounded at one end.
  • Page 26 Instrumentation of the turbine meter The sensitivity of the Preamp rolls off as frequency increases, matching the characteristic output of a turbine meter with inductive pickup. High sensitivity at low frequencies allows the turbine meter to operate at its lowest possible flow rates. Reduced sensitivity at high frequencies prevents spurious counting due to RFI and transients.
