Ask A Question

Description & Features

The WEBTEC CT Series Turbine Flow Meters, specifically the CT300-MA-S-S-6 model, are engineered for precise flow measurement in hydraulic systems, offering a maximum flow rate of 300 L/min (80 US gpm) and withstanding pressures up to 420 bar (6000 psi). With a flow accuracy of ±1% full scale, these meters ensure reliable data for your use. They function efficiently within fluid temperatures ranging from 5 to 90°C (41 to 194°F) and ambient temperatures between 5 to 40°C (41 to 104°F), making them versatile for various environments.

Constructed with durable materials such as aluminum and stainless steel, and equipped with FKM/EPDM seals, the CT Series is designed for longevity and compatibility with mineral oils as per ISO 11158 standards. The meters feature M12 5-Pin electrical connections and require a power supply of 12 to 32 V DC, with an IP66 rating for excellent dust and water resistance. Main porting is 1-5/16” -12UN #16 SAE ORB with top porting at 7/16” -20UN #4 SAE ORB, enhancing their adaptability in complex systems.

Question by: Dean S on Oct 5, 2025, 5:48 PM
flow range on this one, is 8 L/min really the low end, or can it read lower than that accurately?
Answer by: Customer Support on Oct 7, 2025, 4:19 PM
Eight liters per minute is the bottom of the rated range, and accuracy is specified at plus or minus 1% of full scale across that 8 to 300 L/min window. Below 8 L/min the turbine rotor just doesn't spin consistently enough to hold that tolerance, so readings below that threshold aren't going to be reliable. If your application sits mostly in the lower end of that range, it's worth making sure your normal operating flow stays above the 8 L/min floor to get clean numbers.
