Product Description:

YJJ FS1015CL-100-ISO-C MEMS Thermal Gas Mass Flowmeter 0-100SLPM Medical Equipment

Features:

I. Model Explanation

FS1015CL: SiXiang MEMS thermal mass flow series (without split-flow straight-through structure)

100: Range 0 - 100 SLPM (standard liters per minute, at standard pressure and 20°C)

ISO: ISO15mm medical standard cannula interface (commonly used in ventilators)

C: Dual output: 0.5 - 4.5V analog voltage + IIC digital signal

II. Core Electrical & Performance Parameters

Range: 0 - 100 SLPM, range ratio 100:1 (can measure very small flow rates), minimum startup flow rate < 0.5 SLPM

Accuracy: ±(1.5% reading + 0.2% FS); repeatability ≤ 0.25% FS

Power Supply: DC 5V ± 5%, total power consumption ≤ 50mW (low power consumption, built-in power supply in the device) Output

Simulation: 0.5V (0 flow rate) to 4.5V (full scale 100SLPM) linear voltage

Digital: IIC communication, direct connection to microcontroller/PLC for reading mass flow values

Pressure resistance: Maximum pressure resistance 0.2MPa (2bar), normal working pressure loss ≈ 1300Pa (low pressure loss, no overpressure)

Response speed: ≤ 8ms, rapid capture of instantaneous flow rate

Applicable media: Air, O₂, N₂, medical mixed gas, etc. Clean and dry gases without oil, water vapor, dust

Working environment: 10-55℃, contact material PPS, reusable after medical alcohol disinfection

III. Product advantages

Thermal mass flow measurement, no need for temperature and pressure compensation, directly outputs standard mass flow rate (not affected by temperature and pressure fluctuations)

Straight-through without bypass structure, low pressure loss, does not obstruct the gas path; medical ISO15 quick connection, direct insertion and removal for ventilator pipelines

Small zero drift, high stability, not prone to drift in medical equipment during long-term continuous operation
