#Overview
This series of high-frequency transducers is designed for precise and reliable liquid measurement. Operating at 1MHz and 2MHz, they provide the resolution needed for critical applications in water utilities and industrial process control. With housings made from advanced engineering plastics like PPS+GF and PEEK, they offer excellent durability and chemical resistance for long-term contact with various liquids.
#Key Features
- High-Frequency Operation: 1MHz and 2MHz models deliver high-resolution data for precise flow and level measurement.
- Excellent Chemical Resistance: PPS+30%GF and PEEK housings resist corrosion from a wide range of liquids.
- High-Pressure Construction: Rated for up to 3.5 MPa, suitable for high-pressure water lines and industrial processes.
- Low Ringing Time: Ensures fast signal decay, enabling accurate measurement in confined spaces.
- Narrow Beamwidth: Provides focused signal transmission for improved accuracy and reduced interference from pipe walls.

Q: What is the benefit of a 2MHz transducer over a 1MHz?
A: A 2MHz transducer provides higher measurement resolution and is better for detecting very small flows or bubbles. However, its signal attenuates faster, making it more suitable for cleaner liquids and smaller pipe diameters. -
Q: Can you customize the cable length?
A: Yes, standard cable lengths are provided, but we can customize them according to your project requirements.
