1. GENERAL INFORMATION 1.1 General Vortex Shedding is not new. Da Vinci observed vortex shedding in 1513. Von Karman provided an empirically determined formula for it in 1911-1912. One observes it as eddies downstream of a rock or a piling in a fast moving stream. Yet, it wasn’t until it was successfully developed and installed in the late 1960’s that this significant development in the science of flow measurement was given considerable attention by industry. 1.
1.3 Sensor Operation Two pressure sensing devices are mounted in the pipe wall of the flow meter. Inserted in its center is a stainless steel bluff body, on either side of which alternating stresses are induced in response to the forming and shedding of vortices. The piezo electric sensors detect the pressure pulses, and their energy content is amplified in the preamplifier and processed to furnish an output proportional to the rate of flow. 1.
2.1 Handling Precautions The vortex flow meter has been tested at the factory. When the instrument is received, it should be inspected for damage due to mishandling during shipment. If damage is evident, report it to the carrier immediately and have them present when the case is opened. They are responsible for any damage during shipment. If you have any problems or questions, consult the factory or your local representative. 2.
Piping Table 3.
Note : Straight pipe length on the downstream side to be 5 pipe diameters minimum. *D = Pipe internal diameter. To ensure the high accuracy of flow measurement specified on the identification sheet, piping and installation instructions must be followed carefully. A) The pipe immediately up and down stream of the flow meter must be of sufficient length, straight and free of obstructions. Refer to the piping requirements chart for exact dimensions (Figure 3).
3.5 Orientation FIGURE 4 The flow meter uses piezo-electric sensing elements with no moving parts. This eliminates wear and allows for vertical or horizontal installation. 3.6 Alignment Rings and Gaskets Alignment rings may be provided with the meter and should be used to ensure proper alignment of the flow meter to the pipe flanges. Misalignment can result in percentage errors and can even result in a non-functional meter. Gasket size and correct installation are essential to accurate measurement.
3.8 Installation Procedure The Vortex Wafer flow meter is a flangeless style meter. It is installed between pipe flanges using alignment rings through bolts and gaskets. The inside diameter of the surrounding pipe should be identical to the I.D. of the meter. The following installation procedures should be used to insure proper alignment of the flow meter which in turn will insure accuracy: A) Check the weldmount mating flanges for internal weld bead.

5.3.6.1 Submenu L2 Analog 4-20mA Menus Vortex Flow Meters are equipped with two channels programmable analog 4-20 mA outputs. Each channel can be individually assigned to one of the following process variables: Volumetric Flow, Mass Flow, Temperature*, Pressure*. By default channel #1 is set to Volumetric Flow and channel #2 is set for Mass flow. For each channel 4 mA and 20 mA points, which define the flow meter output range, can be preset to maximize resolution of analog output.
- Diagnostic: Output will be energized when any of the Diagnostic or System events are active - Manual On Control: Output will be energized until Disabled option will be selected. By default both optically isolated outputs are disabled. 5.3.6.3 Submenu L2 RS-485 Address Menus The standard Vortex flow meter comes with an RS-232 interface. For the optional RS-485 interface, two hexadecimal characters of the address must be assigned. By default each flow meter is shipped with RS-485 address 11.
5.3.7.1 Submenu L2 PWM DSP Menu Digital Signal Processing software algorithm can be set to calculate flow rate based on five different methods: a) b) c) d) e) Auto number of pulses over preset measure interval PWM (pulse width measurement) FFT AWD (Analog Watchdog circuitry, for troubleshooting only) By default Vortex Frequency source is set to Auto. In this mode flow meter automatically switching source to best suited algorithm. All methods calculates frequency of the pulses from the flow meter sensor.

8. TROUBLESHOOTING 8.1 Common Conditions Your Vortex Flow Meter was thoroughly checked at numerous quality control points during and after manufacturing and assembly operations. It was calibrated according to your desired flow and pressure conditions for a given fluid. It was carefully packed to prevent damage during shipment.
8.2 Troubleshooting Guide NO. INDICATION 1 LCD Display remains blank when unit is powered up. No response when flow is introduced from analog 4-20 mA. 2 LCD Displays flow reading, but 4-20 mA output signal does not change (always the same or reading around 4.0 mA). LIKELY REASON Power supply is bad or polarity is reversed. SOLUTION Measure voltage on pins 1 and 2 of the TB1 screw terminal connector. If voltage is out of specified range, then replace power supply with a new one.
NO. INDICATION 4 There is no actual fluid flow through the Vortex meter (no flow conditions), but LCD Display reading some flow rate. 5 Erratic Flow rate Reading LIKELY REASON Sensors wires are disconnected from CPU board. SOLUTION Using ESD precautions and hazardous area precautions, remove the electronics enclosure window cover. Remove electronics assembly unit. Disconnect the vortex sensor connector from the CPU board (the CPU board is the board with LCD display) via cut out in the terminal board.
NO. INDICATION 6 The Temperature* reading on the LCD is not correct (out of the device measurement range: -20 to 260C) * - for devices with T/P option. 7 The Pressure* reading on the LCD is not correct (out of the device measurement range or does not react on pressure change in the process line) * - for devices with T/P option.
