Fluid vibration:
For a gas line which uses a position-type or roots-type blower compressor or a high-pressure liquid line (about 1MPa or more) which uses piston-type or plunger-type pump, fluid vibrations may be produced.
In these case, install valve on the upstream side of digitalYEWFLO. For inevitable fluid vibration, put a vibration damping device such as throttling plate or expansion section in the upstream side of digitalYEWFLO.

Piston-type or plunger pump:
Install the accumulator on the upstream side of digitalYEWFLO to reduce uid vibrations.

Valve positon (T-type piping exist):
When pulsation causes by a T-type piping exist, install the valve on the upstream of the owmeter.
Example: As shown in the figure, when the valve V1 is turned off, the fluid flow throught B as to meter A the flow is zero. But due to the pulsating pressure is detected, the meter is zero point become uctuating. To avoid this, change the valve V1 location to V1'.
Note: In case of the Reduced Bore Type, moisture may be remained upstream of the owmeter. Drain it appropriately.

• Piping for Avoiding Bubbles
Flows containing both gas and liquid cause problems. Avoid gas bubbles in a liquid ow. Piping should be carried out to avoid bubble generation.
Install the valve on the downstream side of the owmeter because pressure drop across the control valve may cause gas to come out of the solution.
<3. INSTALLATION> 12 (4) Pipeline Diameter and digitalYEWFLO
The process pipeline inner diameter should be slightly larger than the vortex owmeter inner diameter, schedule 40 or lower pipe should be used for 1/2 to 2 inch owmeters and schedule 80 or lower pipes for 3 to 16 inch owmeters.

The vortex owmeter is of IP67, Type 4X, JIS C 0920 watertight protection. However, it cannot be used under water.
3.3 Maintenance of Piping (1) Pipe cleaning
• Flushing of pipe line (Cleaning)
Flush and clean scale, incrustation and sludge on the inside of pipe wall for newly installed pipe line and repaired pipe line before the operation.
• Fluid Carrying Solids
Do not measure uids that carry solids (e.g. sand and pebbles). Make sure users periodically remove solids adhering to the vortex shedder.
• Obstruction of ow uids may cause to make
a chemical reaction and the uid will be crystallized and hardened, and be deposited on the pipe wall and shedder bar.
In those cases, clean shedder bar.

Description
Strip off the outer polyethylene jacket, outer braided shield and inner jacket, and inner braided shield as per the dimensions below.
Strip off the black conductive layer convering two wires completely, as per the dimensions below. Twist each of the conductor and drain wires so that there are no free strands.
Do not short-circuit the conductive layer and the terminals (A, B, C and T*1).
Strip off about 5 mm (0.2 in.) of insulation for each of wires A, B, and T*1, and twist the strands of each wire. Twist the inner and outer drain wires together.
Slide FEP (fluorinated ethylene propylene) tubing over the twisted inner and outer drain wires C until the tubing cannot be slid any further, and then cut off the tubing leaving 5 mm (0.2 in.) of the stranded drain wires exposed.
Slide heat shrinkable tubing over the cable end so that the tubing covers the braided shield and overlaps both the polyethylene jacket and loose wires A, B, C, and T*1.
Slide a short piece of heat shrinkable tubing over each of wires A, B, C, and T*1. Install a crimp-on terminal lug at the tip of each wire. Crimp and solder each lug.
Slide each short piece of heat shrinkable tubing over the crimp sleeve. Heat all pieces of heat shrinkable tubing with a heat blower or dryer.
Attach an identification label to the end of the cable.
NOTE
Check that the insulation resistance between each wire including the inner shield is 10M or greater at 500V DC. Ensure that both ends of the wires are disconnected (open-circuited) during the check.

7.2 Connection Method for the HART Con guration Tool
The HART Con guration Tool can interface with the digitalYEWFLO from the control room, the digitalYEWFLO site, or any other wiring termination point in the loop, provided there is a minimum load resistance of 250 Ω between the connection and the receiving instrument. To communicate, it must be connected in parallel with the digitalYEWFLO, and the connections must be non-polarized. Figure 7.3 illustrates the wiring connections for a direct interface at the digitalYEWFLO site. The HART Con guration Tool can be used for remote access from any terminal strip as well.

8.1.5 Setting of Pulse Output (Scaling)
Pulse output are constructed by two units, that are “Scaled pulse and Unscaled Pulse”.
(1) Scaled Pulse
When SCALED PULSE is selected in B20, set owrate per one pulse output. Rate unit is linking to the ow unit.
(2) Unscaled Pulse
When UNSCALED PULSE is selected in B20, it outputs the pulse calculated by following formula. The formula for output pulse number is as follows. Output pulse number per one second = vortex number per one second / PULSE RATE set number.
Read IM 01F06A00-01EN Section 11.6 “Flow Calculation.”
● Pulse Rate setting
Pulse rate setting is settable by “B21:PULSE RATE”.
<8. OPERATION> 32 8.1.6 Setting of Burnout Switch
digitalYEWFLO is equipped with a CPU error burnout function used to set the output direction upon CPU error, and a sensor burnout function that sets the direction of the output in the event of burnout of the temperature sensor. When factory- shipment under normal conditions, the output of bothCPUerrorburnoutandsensorburnoutare set to HIGH, but if option code /C1 is speci ed, the CPU error burnout is set to LOW(-2.5% below) output, and sensor burnout is set to LOW(-2.5% below) output, respectively. The setting of the direction of output from burnout can be changed. To change the direction of output arising from burnout, switch the setting pin on the CPU assembly(ReadTable8.1).
