COMPANY OVERVIEW
FAQs
How does the 8-hole design help in muddy water?
The multi-hole nose cone helps maintain stable pressure transmission in sediment-rich environments where single-port structures are more likely to clog.
Can the cable support deep-well installations?
Yes. The shielded vented cable is designed for long vertical suspension applications and demanding deep-well environments.
Is the sensor suitable for outdoor hydrological monitoring?
Integrated lightning and surge protection helps improve reliability in outdoor and remote monitoring installations.
How is long-term measurement stability maintained?
The imported piezoresistive sensing element provides stable output performance with long-term stability up to ≤0.1% F.S / Year.
How does atmospheric compensation work?
The vented cable structure automatically balances atmospheric pressure changes to help maintain accurate level measurements.
