ST75V Mass Flow Meter
A compact inline thermal mass flow meter designed for low-flow gas measurement in pipe sizes from ¼” to 1½”.
Ideal for compressed air, natural gas, syngas and other smaller-line gas applications.
The FCI ST75V Thermal Mass Flow Meter is a compact inline thermal mass flow meter designed for accurate gas flow measurement in small pipe sizes and low flow industrial gas applications.
Engineered for precision and installation flexibility, the ST75V incorporates a unique low-pressure-drop flow conditioning design which minimises the requirement for long upstream straight pipe runs, making it ideal for difficult or space-restricted installations.
Using proven thermal dispersion technology, the ST75V measures gas mass flow directly without requiring additional pressure or temperature compensation, providing stable and repeatable performance across varying process conditions.
The ST75V is particularly well suited to:
- Fuel gas injection systems
- Syngas measurement
- Compressed air monitoring
- Process gas measurement
- Industrial utility gases
- OEM skid systems
- Low flow gas applications
Its compact inline design and excellent low-flow sensitivity make it a popular solution where accurate measurement of small gas flows is critical.
Designed for Low Flow Gas Applications
The ST75V is specifically developed for applications where conventional flow technologies may struggle with:
- Low flow rates
- Limited installation space
- Minimal straight pipe availability
- Variable gas conditions
The integrated flow conditioning design helps stabilise the gas profile before measurement, improving performance in compact pipework systems without introducing significant pressure loss.
Reliable Thermal Mass Flow Measurement
The ST75V delivers direct gas mass flow measurement with several operational advantages:
- No moving parts
- Excellent low-flow sensitivity
- Stable measurement across changing gas conditions
- Low maintenance operation
- No pressure or temperature compensation required
This makes it particularly effective in industrial gas systems where reliability and repeatability are essential.
