XGZF4000 — higher-throughput SLM flow

XGZF4000 spans manufacturer-listed options of approximately 5–500 standard liters per minute, a materially different scale from XGZF3000’s sccm applications. Select the calibrated gas, pressure drop across the sensing path and thermal operating conditions based on the chosen order code. Confirm whether the actual module reads bidirectionally and what electrical format the host uses. A reported mass flow must be interpreted in the maker’s standard reference conditions when comparing with a volumetric flow requirement.

XGZF4000 — SLM-Scale MEMS Mass Flow — engineering specifications

Original CFSensor model documentation differentiates the family’s hardware choices. Ranges and options below are manufacturer declarations, not guaranteed simultaneous performance of every part number.

Design item	Manufacturer model evidence	Engineering implications
Technology	MEMS thermal mass flow for industrial gas path	Uses heated-chip heat transfer; gas properties affect indicated reading.
Standard volume rating	Catalogue family 5–500 standard liters/minute (SLM)	Not the 100–3,000 SCCM XGZF3000 microflow class.
Factory options	Unidirectional or bidirectional variants	Reverse-flow measurement must be explicitly supported by ordered sensor.
Output families	Digital and amplified analog choices	Confirm selected SKU serial protocol and calibration curve.
Span choice	5–500 SLM describes different sensor/order families	At the low end, a maximum-scale 500 SLM unit could provide poor useful accuracy.
Response behaviour	Manufacturer describes fast thermal flow response	Verify timing under actual gas pressure, moisture and installation.
Mechanics	Larger gas passage/flow design than XGZF3000	Select port geometry, connection leakage and pressure loss by drawing.
Reference conditions	Standard temperature/pressure and calibration gas must be specified	Actual process flow differs from SLM as conditions vary.

Installation and OEM qualification

For pneumatic equipment or controlled gas mixing, identify whether the quoted standard liters/minute corresponds to maker’s reference state and gas composition; do not relabel SLM as real liters/min without correction. Check the installation’s gas path loss, flow direction, power supply and media cleanliness. Industrial gas-flow suitability does not establish Ex/ATEX certification or readiness for oxygen-enriched or combustible atmospheres; those require a separate safety analysis and the exact OEM approval.
