534FTB Series In-Line Flow Meter
Brand: Kurz InstrumentsThe Series 534FTB is designed with built-in inlet and outlet piping reducers/expanders to produce exceptional immunity to upstream and downstream flow disturbances caused by elbows, valves, and line size changes. The patented technology results in output with exceptional low end-to-end pressure drop and fast response to velocity and temperature changes.
Features- Built-in flow conditioners to accommodate upstream and downstream flow disturbances
- Ideal for process and specialty gases
- Exceptional low end-to-end pressure drop.
- Very low flow noise
- Sensors resistant to dirt and corrosion
- Wide turndown capability
- Zero velocity as a valid data point
