Sensor Module for the FloBossTM 504 Flow
 |
The Sensor Module accumulates single or dual pulse counts from the turbine meter (typically via a preamp) and performs error checking/ correction. In addition, the SM has a static pressure sensor and an optional auxiliary pressure sensor built into it.
The Sensor Module provides volumetric flow measurement for a turbine meter used to measure the flow in a single meter run and can be configured for Metric or English units of measurement. The Sensor Module provides terminals for its pulse counter (PI) inputs from a turbine meter, and senses static (line) and auxiliary pressures from direct process connections.
The primary inputs used for turbine flow calculations are pulse counter, static pressure, and temperature. The single or dual pulse-count inputs are taken from a single-rotor turbine meter, the static pressure input comes from a process connection to the Sensor Module (SM), and the temperature input is acquired directly from an RTD probe.
The SM can count pulses acquired from a turbine meter, read and convert pressure, store the pulse count and the pressure values temporarily, and communicate the values to the FloBoss.
