Product Description

Non-Contact Ultrasonic Level Transmitter - Reliable & Cost-Effective Liquid Level Solution

Simplify your level monitoring. HHD ultrasonic level meters provide a perfect balance between performance and value. By using high-frequency sound waves, these sensors measure liquid levels without ever touching the medium, eliminating the risk of corrosion and sensor fouling. Ideal for water treatment, chemical storage, and open-channel monitoring, our ultrasonic series is the go-to choice for thousands of industrial plants worldwide.

Core Features of HHD Ultrasonic Series:

• Non-Contact Measurement: No wear and tear; perfectly suited for corrosive, sticky, or ultrapure liquids.

• Automatic Temperature Compensation: Built-in algorithm adjusts for speed-of-sound changes to maintain precision in varying weather.

• Intelligent Echo Processing: Advanced "false echo" filtering technology ensures stable readings even in tanks with minor obstructions.

• IP67/IP68 Waterproof: Fully sealed probe design, capable of withstanding outdoor rain and humid environments.

• Compact All-in-One Design: Easy to install (Integrated type) or remote monitoring (Split type) options available.
   

  Typical Applications 

• Water & Wastewater: Monitoring sump pits, reservoirs, and sewage treatment tanks.

• Chemical Storage: Non-contact measurement of acids, alkalis, and solvents (using PTFE probes).

• Open Channel Flow: Working with flumes (Parshall/Weir) for irrigation and drainage measurement.

• Food & Beverage: Level control in juice, milk, and beverage storage tanks.

We can also provide:
1. Localized technical services
2. Door to door delivery service
