Accordingly, proper flow straightening measures must be taken when the application engineer considers installation of a Delta meter. 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. But if you plan to solve the flow pattern problem with a...
D-585--E (3) Space Saving Arrangement If required straight pipe space is not obtainable 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 to avoid the space problem. Honey Vane Outline Dimensions ● Dimensions in millimeters Nom. Honey Vane S Honey Vane L φ...
D-585--E 5.4 Pulsation Compressors, Roots blowers and other pulsation pressure generating sources could adversely affect meter performance. Minimize pulsating pressures by referring to the following formula: N <.5 ρV (mmH where N : Pulsation pressure (mmH ρ : Density (kg/m V : Minimum velocity (m/s) If pulsation pressure is excessive, the following measures should be taken into consideration: Locate the source of pulsation downstream of the meter or locate it as far from the meter as possible. ➀...
D-585--E 5.7 Prevention of Slug Flow This meter can measure both gases and liquids, but slug flows (where gases exist in the process liquid) will produce a loss of metering accuracy. 5.8 Keep the Pipe Filled with Process Fluid When making a liquid measurement, ensure that the piping remains full of the process liquid. Installation in locations where it is difficult to keep the piping filled with the process liquid, or where bubbles tend to collect should be avoided. 5.9 Bypass Line For maintenance and servicing purposes, it is a Valve in Bypass Line...

D-585--E 6.4.2 Installation Procedure (See assembly drawing in Fig. 6.5 on page 14 and Fig. 15.1 on page 40.) By turning in or out the handwheel, the probe of this flowmeter goes down or up and, without the need of interrupting the line, it can be drawn out. When the meter is placed in service for measurement, the hold- down disc is so positioned as to come in contact with the retaining ring (the guide is at match mark “A” on the stud). During maintenance or inspection, allow the probe to be housed completely in the short pipe (the guide is at match mark “B” on the stud) and remove the meter from above the gate valve. When removing or installing it, exercise care to minimize the possibility of unexpected trouble by observing the following instructions: (1) Install the hold-down disc in the right physical orientation.
D-585--E Removal Procedure (1) Disconnect wiring of the preamplifier. (2) By turning the handwheel, retract the probe. Retract it until the guide arrives at match mark “B” on the stud. (3) Confirming that the probe has been retracted completely, fully shut off the gate valve. (4) Taking precautions against internal pressure, carefully open the vent valve, allowing the internal pressure to escape. (5) Dismount the flowmeter from the gate valve. 6.4.3 Preamplifier Orientation As viewed from the direction of flow (upstream Display Preamplifier side), the preamplifier typically installs inclined to...
D-585--E 6.6 Ambient Temperature Given in Fig. 6.9 is the allowable process fluid temperature relative to the ambient temperature. Ensure that the ambient temperature is held within Nonexplosionproof Rated the rating. Explosionproof Rated If there is a possibility that the ambient temperature exceeds the allowable limit, the following measures Allowable should be taken into consideration.
D-585--E 6.9 Hottap Type Drive Unit Removal The drive unit (retractable assembly including the handwheel and screw shaft) can be separated. It is beneficial in applications where line vibration is great, or where a single drive unit is shared by multiple flowmeters.
D-585--E 6.10 How to Change Preamplifier Orientation The preamplifier can be oriented to the desired 90° direction in 90°steps as shown in Fig. 6.11. NOTE: T o change the orientation, hex key (JIS B 4648), nominal size 4, is required. The preamplifier can be rotated by loosening its four hex socked head screws, but be sure to disconnect sensor leads before attempting to rotate it.
D-585--E 6.11 How to Change Indicator and Totalizer Orientation If the preamplifier is equipped with local display (indicator and totalizer), the display assembly can be rotated to the desired direction in 90°steps through 360°. By changing the angle of display assembly (internal assembly), the indicator or totalizer appears for maximum readability on a vertical run or a horizontal run.

D-585--E 11. FLOW SENSITIVITY ADJUSTMENT PROCEDURE Flow sensitivity is accurately adjusted over the Potentionmeter specified flow range before the meter leaving the Potentionmeter factory. However, in cases where the sensor has been replaced or if the receiving instrument registers erratic counts at meter shutoff due to noises caused by pipeline oscillation, for example, sensitivity readjustment will be required.
Receiving TP+ TP − Instrument (Power) Pulse Generator mA Meter (for analog type) (Open collector output) Preamplifier Fig. 12.1 About Pulse Generator ■ Illustrated diagrammatically is the test setup if OVAL pulse checker (Model PC2201 is available as a pulse generating source). Also refer to the pulse generator instruction manual. Pulse Checker Switch Settings → 0. C • OUTPUT → 0.5 • WIDTH → 100% • SETTER → 1 to 10K (chosen according to the frequency established)
D-585--E 12.2 Full Scale Frequency Calculation The full scale frequency of unfactored pulse equivalent to the full scale flowrate is calculated by the following formula: Full Scale Flowrate (volume unit/hour) Full scale frequency (Hz) = × Meter Factor (volume unit/P) 3600 NOTE: F ull scale flowrate must have the same unit of measure as meter factor. The full scale frequency established before shipment from the factory is stated in ANALOG F.S.
D-585--E 13. MAINTENANCE As long as your Delta meter is placed in service under proper operating conditions, it will perform satisfactorily over extended periods of time. But scale, sludge and other foreign matter contained in the metered fluid could adhere to the inner walls of your meter and degrade meter performance in time. For this reason, periodic disassembly and inspection is suggested. 13.1 Disassembly and Inspection Guidelines ◇ Time for disassembly and inspection ◇ (1) Six months after the first time operation.
