Specifications and Reference Data
3 kA crest (8 ϫ 20 s)
6 kV crest (1.2 ϫ 50 s)
6 kV/0.5 kA (0.5 s, 100 kHz, ring wave)
Security lockout
When the security lockout jumper is enabled, the electronics will not allow you to modify
parameters that affect flowmeter output.
Output testing
Current source
Flowmeter may be commanded to set the current to a specified value between 4 and 20 mA.
Frequency source
Flowmeter may be commanded to set the frequency to a specified value between 0 and 10000 Hz.
Low flow cutoff
Adjustable over entire flow range. Below selected value, output is driven to 4 mA and zero pulse
output frequency.
Humidity limits
Operates in 0–95% relative humidity under non-condensing conditions (tested to IEC 60770,
Section 6.2.11).
Overrange capability
HART analog
Analog signal output continues to 105 percent of span, then remains constant with increasing flow.
The digital and pulse outputs will continue to indicate flow up to the upper sensor limit of the
flowmeter and a maximum pulse output frequency of 10400 Hz.
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 interchangeability of electronics
and/or sensors without calculations or compromise in accuracy of the calibrated meter body.
