HART Vortex / Swirl Flowmeter H880TH is designed for HART vortex/swirl flowmeters, which uses piezo sensor. Please read this manual carefully before use H880TH. Please followthismanual to completeyour operation.Ifyou have any questions, please do not hesitate to contact us. We willreplyas soon as possibleand resolveyour problem. Product Description APPLICATION Used for Piezo sensor a) Power supply: 9 -32VDC b) Output: 4~20mA with HART (2-wire) c) Configuration: Flow mode, Flow unit, Range (Qmax), Density, Display, etc. d) Alarm: Low alarm will output 3.8mA, high alarm will output 22.0mA. e) K-Factor linearity: H880WJ provides 2 to 5 points k-Factor correction. f) Local adjust functions: Setting range and PV unit, Density, Flow mode, damping, high alarm percent, low alarm percent and data recovery etc. g) Two-line LCD display: Instant flow rate and totalized flow value can be displayed simultaneously with high-brightness backlight. h) Restore factory settings: If the damping value entered is ‘05678’, it will automatically perform ‘restore factory settings’. i) Input frequency ranges :0.5Hz ~ 4KHz j) Operating temperature: -20°C ~ +70°C(with LCD) k) Intrinsically Safe:EXia II CT6
