  • Page 4: Before You Begin

    D-160TS-7-E 1. BEFORE YOU BEGIN 1.1 Confirming the Specifications （1）Once the flowmeter is received, inspect its appearance and confirm that it is not damaged during transit. （2）Product code and specifications are indicated in the nameplate of the flowmeter. Make sure that information on the nameplate conforms to your particular specifications.

  • Page 5: Operating Conditions

    Read them carefully before you place the meter in service. [Example of Converter Nameplate] 3. GENERAL DESCRIPTION The OVAL VORTEX FLOWMETER is a vortex flowmeter with thermistor sensors, designed for gas measurement. Downstream of the bluff body, von Karman vortices form and shed alternately proportional to the rate of flow on either side of that triangular body placed perpendicular to the stream of flow.

  • Page 6: Principle Of Operation

    D-160TS-7-E 4. PRINCIPLE OF OPERATION As a stream of fluid runs through the pipe, von Karman's vortices form and shed proportionally to the flowrate downstream of the bluff body located perpendicular to the stream of flow. Thermistor sensors in the sensor housing pick up these Karman vortices.

  • Page 7: Construction (Component Names And Functions)

    D-160TS-7-E 5. CONSTRUCTION (Component Names and Functions) （1）Sensor ① Meter body assembly It consists of a measuring pipe and a bluff body. As the metered fluid runs, Karman vortices form and shed downstream of the bluff body. ② Sensor assembly The assembly contains sensors to detect Karman vortices.

  • Page 8: Piping Instructions

    Accordingly, proper flow straightening measures must be taken when installing the OVAL VORTEX FLOWMETER. In applications where OVAL straightening devices (flow straightener, Honey vane, and downstream pipe) are used, a straight pipe section is not required unless otherwise specified.
  • Page 9 （3）Space Saving Arrangement If required straight pipe length is not available upstream of the vortex flowmeter due to existing restrictions on installation location, the OVAL Honey Vane S combined with a short pipe may be used for space saving. ● Honey Vane Outline Dimensions Unit：mm...

  • Page 10: Pipes To Be Used

    D-160TS-7-E 6.2 Pipes to be Used Upstream and downstream pipes adjacent to the flowmeter should be of the same internal diameter (ID) as the flowmeter. (The exclusive flow straightener, Honey Vane L, and downstream short pipe have the same ID as the flowmeter.) The table below shows the standard ID of the flowmeter.

  • Page 11: Meter Installation

    D-160TS-7-E 6.5 Meter Installation To prevent troubles such as adverse effects on meter accuracy and gas leaks, the following should be taken into consideration when installing the meter: ① Make sure that the flow direction conforms to the arrow mark on the meter.

  • Page 12: Lagging Work

    D-160TS-7-E 6.6 Lagging Work If temperature of the measured fluid exceeds 60℃ , even with explosionproof enclosure, the flowmeter must be insulated thermally (lagging).
