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 flow variable, percent of range, current output, and/or totalized flow.
Enclosure Rating
NEMA Type 4X; CSA Type 4X; IP66
Failure Mode Alarm
HART Analog - If self-diagnostics detect a gross flowmeter failure, the analog signal will be driven either below 3.75 mA or above 21.75 mA to alert the user. Also, high or low alarm signal is user-selectable through the fail mode alarm jumper on the electronics.
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.
Transient Protection
The optional transient terminal block prevents damage to the flowmeter from transients induced by lightning, welding, heavy electrical equipment, or switch gears. The transient protection electronics are located in the terminal block.
Security Lockout
When the security lockout jumper is enabled, the elctronics will not allow you to modify functions that affect flowmeter output.
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.
