Yokogawa Vortex Flowmeter DY250-DALBJ4-0D
Overview:
Yokogawa Vortex Flowmeter DY250-DALBJ4-0D
digitalYEWFLO, combines the field proven sensor and body assembly used in more than 300,000 units installed worldwide, with an unique digital electronics including SSP (Spectral signal processing)* technology.
digitalYEWFLO provides high accuracy and stability, even in harsh process conditions. Combined with high reliability and robust design, it delivers improvements in plant efficiency and reduced operating costs. digitalYEWFLO Multi-Variable Type (OPTION:/MV)
build in temperature sensor, so that temperature measurement and Mass Flow calculation is available. digitalYEWFLO Reduced Bore Type (OPTION:/R1, /R2) Integrated and casting construction with concentric reduced bore piping.
It benefits piping cost reduction and lower flow range.
* SSP is YOKOGAWA’s original technology for digital signal processing.

Refer to Option Specifications
|
* 1 : Output signal code ‘-E’: HART 5. (Output signal code ‘-J’ is recommended for HART communication.)
* 2 : Output signal code ‘-J’: HART 5 or HART 7 selectable. Specify HART 5 or HART 7 when ordering.
* 3 : For FOUNDATION Fieldbus protcol, refer to GS 01F06F01-01E. For Fieldbus communication type, there are not setting keys on the display board.
* 4 : In case of A (JIS SCS14A), the process connection is available for JIS (AJ1, AJ2, AJ4, BJ1, BJ2, BJ4)
* 5 : In case of B (ASTM CF8M), the process connection is available for ANSI (AA1 to 4, BA1 to 5, BS1 to 5, CA4 to 5) and DIN (AD1 to 4, BD1 to 4).
* 6 : Refer to Table 1. In case of /NC or /HY or /HT or /LT, select X (others).
* 7 : Refer to Table 1. In case of /NC or /HY or /HT or /LT, select X (others).
* 8 : Users must consider the characteristics of selected wetted parts material and the influence of process fluids. The use of inappropriate
materials can result in the leakage of corrosive process fluids and cause injury to personnel and/or damage to plant facilities. It is also possible that the instrument itself can be damaged and that fragments from the instrument can contaminate the user's process fluids.
Be very careful with highly corrosive process fluids such as hydrochloric acid, sulfuric acid, hydrogen sulfide, sodium hypochlorite, and high- temperature steam (150°C [302°F] or above). Contact Yokogawa for detailed information of the wetted parts material.
* 9 : Refer to Table 2.
*10 : In case of an explosion protect type, it depends for an electrical connecion on the kind of an explosion protect type. Refer to “ OPTION SPECIFICATION (HAZARDOUS AREA CLASSIFICATIONS)”
*11 : In case of /FF1 or /CF1, the screw length is deeper than ANSI standard for 0.5 to 3.5 threads.
*12 : Indicator is not available for remote type detector.
*13 : DY250-DALBJ4-0DA- /MV and DY250-DALBJ4-0D -N***/MV should be combined.
*14 : One set of end finish part is attached.
*15 : DY250-DALBJ4-0DC Cable can be used up to 30m. When you divide the cable below 30m, select the Cable End code [-0].
