Vortex PhD In-Line Vortex Flow Meter

Vortex PhD™ In-Line Vortex Flow Meter
»Features »Specifications »Installation »Model Codes
 
EMCO's model Vortex PhD® is an in-line vortex shedding flow meter capable of measuring liquids or gases, including steam, for pipe sizes from 1" to 12", available in stainless steel and carbon steel. The PhD flow meter has no moving parts, rugged construction, and microprocessor-based electronics for high accuracy in many flow metering applications. The Vortex PhD flow meter, with no moving parts, provides accurate measurement with lower maintenance, and lower total cost of ownership than other flow meter technologies.

Installation

Installation Specifications
Mounting Install flow meter vertically, horizontally, or at any angle. For liquid service, the flow line must be full during flow meter operation; in vertical lines, flow direction should be upward for optimum flow meter performance.
Straight run piping (D = internal diameter of pipe) Upstream Downstream
One 90° elbow before meter 10 D 5 D
Two 90° elbows before meter 15 D 5 D
Two 90° elbows out of plane before the meter
30 D
5 D
Reduction before the meter 10 D 5 D
Regulator or valve partially closed before the meter
30 D
5 D
Pressure and temperature taps Mount pressure tap 3.5 to 7 pipe diameters downstream of the flow meter. Mount temperature tap an additional 3.5 to 7 pipe diameters downstream of the pressure tap.
Site selection Select installation location to minimize turbulence and swirl. The piping configuration, i.e., valves, elbows, pumps, may add disturbances to the flow.
Serviceability The sensor element can be removed, and replaced, without removing the flow meter body from the process line and without process shutdown for process pressures below 750 psig (52 barg).

PhD-90-S-60-F-300-LOC-TOT-RMT-T represents a 6" in-line vortex flow meter with stainless steel wetted parts, for steam or gas applications, with ANSI class 300 flanged connection, a local indicator and totalizer, with remote-mounted transmitter, and teflon sensor wires.

Notes:

  1. Wafer-style meters available in stainless steel (sizes 1 to 4" only).
  2. Has 4 to 20 mA and/or 50% duty cycle frequency output. A 50% duty cycle frequency can be scaled.
  3. FM and CENELEC approved meters come with a magnet wand. For all other meters the wand can be ordered as an option.
  4. At least one local indicator is recommended at each site. If one display will be used on many meters, display boards should be purchased separately.
  5. Remote-mount electronics are required for high process temperatures (refer to the general specification). The standard remote-mount option comes with 30' of cable.
  6. Not available with European CE Mark or FM, CSA and CENELEC approvals.
