Spot Japanese Yokogawa flowmeter

Spot Japanese Yokogawa flowmeterBasic technical specifications:

New features with SSP (Digital Signal Processing) technology
SSP is a part of the digital vortex flowmeter circuit. SSP can analyze the fluid situation inside the digital vortex flowmeter and automatically make adjustments based on the usage conditions using the analyzed data. SSP can correctly detect vortices in low flow areas, thereby significantly improving measurement stability. This feature is a digital signal processing technology developed by Yokogawa Corporation in Japan, which has never been present in previous vortex flowmeters.
Good self diagnostic function
Capable of identifying and displaying usage conditions such as significant pipeline vibrations and abnormal flow patterns.
High precision
± 0.75% of reading (liquid)
± 1% of reading (gas, steam)
Large temperature range
High temperature type: can reach up to 450 ° C
Low temperature type: the lowest can reach -200 ° C
Simple parameter setting
Frequent use of parameter combinations in one module reduces parameter setting time.
Clear and concise display
Can display traffic, cumulative traffic, and self diagnostic information simultaneously.
Analog/pulse dual output
Simultaneously output flow signal and pulse signal
Alarm output
If an alarm occurs, an alarm signal will be output.
Status output (flow switch function)
When an alarm occurs, the contact outputs an alarm signal. In addition, when the flow rate is lower than the set value, a signal can be output through the contact.
Compact converter structure
Equipped with BRAIN/HART communication and panel setting buttons
Sensors with the same structure can be used to measure liquids, gases, and vapors
Stainless steel sensor without moving parts, durable and safe
Complies with NACE standards
Compliant with NAMUR 43 standard
The maximum length of the separated cable is 30m
Explosion proof structure: JIS/FM/ATEX/CSA/SAA (explosion-proof/intrinsic safety)

Spot Japanese Yokogawa flowmeterBasic performance indicators
Tested fluids: liquid, gas, vapor (avoid multiphase flow and adhesion)
Measurement flow range: see general specification sheet
Accuracy: ± 0.75% of reading (liquid), ± 1% of reading (gas, vapor)

Repeatability: ± 0.2% of the reading
Calibration: The flowmeter undergoes water calibration before leaving the factory

Normal working conditions:
Fluid temperature range: -40~260 ° C (general type)
-200~100 ° C (low temperature type, selected)
-40~450 ° C (high temperature type, selected)
Operating pressure range: -0.1Mpa (-1kg/cm2)~flange rated value
Environmental temperature range: -40~85 ° C (separated sensor, separated converter)

Power supply voltage: 10.5~42V DC (see the relationship diagram between power supply voltage and load resistance)
Electrical performance: Due to the use of common terminals for pulse output, alarm output, and status output, these functions cannot be used simultaneously.
Output signal: Dual output (can simultaneously obtain analog and transistor contact output signals). In this case, refer to the power supply and pulse output wiring in the "Installation Instructions" section.
Analog output: 4~20mA DC, 2-wire system
Transistor contact output: collector open circuit, 3-wire system
Use parameter settings to select pulse, alarm, or status output.
Contact rating: 30V DC, 120mA DC
Low level: 0~2V DC
Communication conditions:
Communication signal: BRAN or HART communication signal (superimposed on a 4~20mA DC signal).
Communication line conditions: Load resistance: 250~600W (including cable resistance)
Power supply voltage: 16.4~42V DC is used for digital communication BRAIN and HART protocols (intrinsic safety type is 16.4~30V DC). Distance from other power lines: greater than 15cm (avoid parallel wiring).
