Micro Motion F100SB18CQBAEZ1ZZ Mass Flowmeter Unit

Module Feature

F100SB18CQBAEZ1ZZ is Micro Motion F100 series compact Coriolis mass flowmeter.

It adopts dual bent-tube Coriolis sensing structure, directly measures mass flow, fluid density and process temperature simultaneously, no need for temperature and pressure compensation. Wetted parts are 316L stainless steel, compatible with most liquid, gas and homogeneous slurry media. It supports HART digital communication, and can be paired with local display transmitter or remote electronics. It has high turndown ratio and excellent anti-vibration performance, widely used for custody transfer, batch control and continuous flow monitoring of chemical, oil & gas and food & beverage plant. It is stocked as critical process instrument maintenance spare.

Working principle

Drive circuit excites the two flow tubes to vibrate at resonant frequency.

When fluid flows through the tubes, Coriolis force generates phase shift between the two vibrating tubes. The phase difference is proportional to mass flow rate; vibration frequency changes with fluid density. The pickup sensors capture vibration signal and send to transmitter electronics for calculation, output 4-20mA analog and digital bus signal to DCS/PLC. The meter continuously monitors tube vibration amplitude, drive gain and sensor health status.

Onboard components

Dual measuring flow tubes, drive coil, pickoff sensing coils, hermetically sealed sensor housing, process flanged connections, internal temperature RTD, wiring terminal enclosure and corrosion resistant coating.

LED indicators

Status LED located on matched transmitter assembly, indicating power, flow active, density valid, drive fault and sensor alarm.

Hardware self‑diagnosis

Built-in supervision detects sensor coil open/short, drive gain out of limit, tube excitation failure, temperature sensor fault and signal loss. Configuration, zero calibration and fault checking are completed by Micro Motion ProLink software.

Programming software

ProLink, used for flow calibration, density trim, HART address setting, zero adjustment and event log reading.
