Name ID Label Description Type Access Class
max_zero 40A6 Zero time The number of readings collected from the sensor during an Auto Zero operation. R/W Unsigned 4
conv_lim 40A7 Converg. limit A unitless number that allows the user to reject the Auto Zero operation if the standard deviation is greater than 10 times the programmed convergence limit. A convergence limit of zero disables this feature. R/W Float 16
pulse_width 40A8 Max pulse width For the RFT9739, a programmable time period, in seconds, that defines the crossover frequency for the frequency output, where Crossover freq. = 1 / (2 x Pulse width). Below the crossover, the output has a constant ON state, and an OFF state that varies with frequency. R/W Float 512
control 40A9 Control output An output that produces 0 V ON and 15 OFF digital levels. The control output can represent faults, zero in progress, flow direction, event 1 or event 2. R/W Enum 1024
tempcal 40AA Temp cal factr A 14-character factor that describes the slope and offset of the linear output representing flow tube temperature. R/W ASCII 32
rt_zero 40AB Zero A value, in microseconds, representing the phase shift between velocity signals from the sensor when measuring zero flow. R Float 2
zero_offset_units 40AC Zero units Units for zero offset - always microseconds. R/W Unsigned 32
rt_sigma 40AD Std dev A unitless value which characterizes the amount of deviation between readings during an Auto Zero operation. R Float 2
fault_code 40AE Fault indicator Downscale: An analog output goes to 0 or 2 mA, the frequency = 0 Hz. Upscale: Milliamp outputs = 22 mA, the frequency output = 15 kHz. Last measured value: Outputs = value measured immediately before before fault. Internal zero: Outputs tied to flow = zero flow. R/W Enum 4
timeout 40AF Slug duration A programmable time period, from 0.00 to 60.00 seconds, during which outputs representing flow hold their last measured value before indicating slug flow. R/W Float 4
