Miniature Ultrasonic Level Transmitter

What It Is

A miniature ultrasonic level transmitter designed for tight spaces and high precision. It measures liquid or solid levels without touching the material – no fouling, no clogging, no moving parts.

Its claim to fame? A blind zone under 6 cm – the smallest of any Chinese ultrasonic level product – plus ±1 mm accuracy.

Key Features (Short & Sweet)

• Blind zone: <0.06 m – mount it very close to the surface

• Accuracy: ±1 mm to ±1.5 mm – precise enough for critical applications

• Compact size: Φ28 mm × 100 mm, M30 thread – fits almost anywhere

• Housing: 304 stainless steel or copper‑plated – rugged and corrosion‑resistant

• Outputs: 4‑20mA, 0‑10V, RS485 (Modbus), or switch – pick what you need

• Temperature compensation: automatic – stable readings in changing conditions

• Power: DC 12‑24V, ultra‑low power (<1.5W)

• Explosion‑proof: Ex ia IIB T4 Gb – safe for hazardous areas

Typical Applications

• Shallow tanks, narrow sumps, and confined spaces

• Water treatment, pump stations, and sedimentation tanks

• Food and beverage tanks, grain silos

• Mining slurries and industrial chemical storage

Why Choose This One

• Smallest blind zone – measure closer than any other ultrasonic

• High precision – 1mm resolution for demanding jobs

• Non‑contact – no maintenance, no wear, no contamination

• Flexible – multiple outputs fit any control system

• Compact – install where others simply won't fit
