insertion Thermal Gas Mass Flowmeter
Measure gas mass flow directly—without the need for temperature or pressure compensation
Approved by：CE, SIL-3, ATEX Explosion-proof certification
-
Reliable Accuracy Under Varying Conditions — With direct mass flow measurement, your readings remain stable even when process temperature or pressure fluctuates.
-
Minimal System Interference — Its insertion-style probe design ensures measurement with virtually no pressure drop and no moving parts, so maintenance requirements are low and operational impact is minimal.
-
Fast Installation, Low Downtime — The hot-tap version enables live installation and servicing, so you don’t need to shut down production to install or maintain it.
-
Flexible Integration — Standard outputs (analog & digital) and signal interfaces mean straightforward connection to your PLC or DCS systems.
-
Durable Build for Harsh Environments — With robust materials and optional explosion-proof certification, it fits rugged industrial settings reliably.
- Wide Measuring Range: Ideal for both low-velocity gas leak detection and large process pipelines
- Hot-Tapped Insertion Design: Allows online installation and maintenance without stopping production — saving time and reducing downtime costs.
