880cr reducer flowmeter rosemount ultrasonic vortex

Available in wafer, flanged, dual, and reducer designs. The Reducer Vortex extends the measurable flow range, reduces installation costs, and minimizes project risk.

  • An all welded non-clog design eliminates ports and gaskets.
  • A pateneted Adaptive Digital Signal Process (ADSP) provides vibration immunity.
  • The 8800CR also has a unique isolated sensor design that allows replacement without breaking the process seal.
  • Troubleshooting is simplified through device diagnostics.

Process Temperature Limits
Standard: -40 to 450oF (-40 to 232oC)
Extended: -330 to 800oF (-200 to 427oC)

Power Supply
HART Analog - External power supply required. Flowmeter operates on 10.8 to 42 V dc terminal voltage (with 250-ohm minimum load required for HART communications, 16.8 V dc power supply is required)

Foundation Fieldbus
External power supply required. Flowmeter operates on 9 to 32 V dc, 17.8 mA nominal, 19.0 mA maximum.

Power Consumption
One watt maximum

Optional LCD Indicator
Displays current output, flow variable, percent of range, and/or totalized flow.

Enclosure Rating
NEMA Type 4X; CSA Type 4X; IP66

Failure Mode Alarm
HART Analog - Self-diagnostics, high or low alarm signal, fail mode alarm jumper.
NAMUR-compliant alarm limits are available through the C4 or CN Option.
NAMUR-compliant limits are 3.6 mA (low) or 22.5 mA (high).

Foundation Fieldbus - The AU block allows to the user to configure the alarm to HI-HI, Hi, LO, or Lo-LO with a variety of priority levels.

Dampening
Adjustable between 0.2 and 255 seconds

Response Time
Three vortex shedding cycles or 0.2 seconds, whichever is greater, maximum required to reach 63.2% of actual input with the minimum dampening (0.2 seconds).

Turn-on Time
HART Analog - Less than four (4) seconds plus the response time to rated accuracy from power up.
Foundation Fieldbus - Performance within specifications no greater than 10.0 seconds after power is applied.

Flow Calibration
Meter bodies are flow-calibrated and assigned a unique calibration factor (K-factor) at the factory. The calibration factor is entered into the electronics, enabling inerchangeability of electronics and/or meter bodies without calculations or compromise in accuracy.

Transient Protection - OPTIONAL
The optional transient terminal block prevents damage to the flowmeter from transients induced by heavy electrical equipment, lightning, welding, or switch gears. Located in the terminal block.

Security Lockout
The elctronics will not allow you to modify functions that affect flowmeter output when the security lockout jumper is enabled.
