OPTIMATION BTOOM11241 Flow Control Module

Module Feature

OPTIMATION BTOOM11241 is a digital gas flow control module. It adopts thermal mass flow sensing principle to achieve stable and repeatable gas flow control. Compact structure, integrated proportional control valve, good corrosion resistance, compatible with multiple high purity process gases. Widely applied in industrial gas distribution and semiconductor gas panel.

Working principle: Thermal flow sensor detects real-time gas mass flow. Built-in control circuit adjusts proportional valve opening continuously to keep flow consistent with target setpoint via closed-loop feedback. Onboard components: Thermal sensing element, proportional control valve, digital control PCB, metal flow manifold, compression fittings, multi-pin electrical connector

Mechanical & Structure

Mounting:Gas panel surface mounting Protection class:IP40

Environmental

Operating temperature:10℃ ~ +50℃ Ambient humidity:5~95% non-condensing Certification:CE compliant Status:OPTIMATION series flow control module

System compatibility

Installed inline on gas pipeline, can work with pressure gauge and pressure controller for complete gas delivery control system.

Function

BTOOM11241 flow control module manufactured by OPTIMATION. It realizes automatic closed-loop gas mass flow regulation. Valve seat wear or sensor contamination will lead to flow drift and unstable control. It is precision gas flow component for industrial and semiconductor gas delivery panel.

Installation

Follow lockout/tagout safety procedure before installation. Isolate gas pipeline and release residual gas pressure. Mount module inline following marked flow direction. Connect 24V DC power and signal cable. Complete gas leak test, zero and span calibration before production startup.

Interface

Metal seal inlet and outlet compression fittings, multi-pin D-sub connector for DC power and control signal, status LED indicators on housing of BTOOM11241.

Diagnostic

Flow reading drift: Sensor contamination or zero offset shift. Unstable flow: Valve seat wear or inlet pressure fluctuation. No control response: Power loss or communication wiring fault. Gas leakage: Fitting loose or manifold seal damage.
