Dayu Split-Type Ultrasonic Level Meter
Product Overview:
Split-type ultrasonic level meters and ultrasonic material level meters feature a separate sensor and main unit, making them ideal for installation on storage tanks, silos, and mounting brackets. They provide a low-cost solution for measuring liquids, slurries, and solids in industrial applications, and are widely used in water treatment, municipal engineering, chemical processing, metallurgy, and machinery manufacturing industries.
The GPRS wireless ultrasonic level meter (for material and liquid level measurement) is a non-contact, highly reliable, cost-effective, and easy-to-install-and-maintain level measurement instrument. It meets most level measurement requirements without contacting the medium and is mainly used in applications where wiring is restricted or unavailable.

II. Operating Requirements
1. Good mobile signal coverage from China Mobile or China Unicom is required at the site. Data is transmitted via the data plan of a China Mobile or China Unicom SIM card. China Telecom SIM cards are currently not supported.
2. On-site measurement conditions must meet the requirements for ultrasonic level meter measurement.
3. Installation must comply with the measurement conditions for ultrasonic level meters.
4. The main unit of the GPRS wireless ultrasonic level meter must have adequate sunshade and rain protection.
5. The cable between the sensor and the main unit must be properly protected against abrasion or damage.

V. Parameters Required for Model Selection
1. Type of medium to be measured: liquid or solid.
For liquids: whether the liquid surface has steam, mist, foam, waves, agitation, or floating objects;
For solids: whether dust is present.
2. Minimum to maximum temperature and minimum to maximum pressure of the medium.
3. Corrosiveness of the medium; if installed inside a tank, the tank material and whether it has an anti-corrosion lining must be known.
4. Whether explosion-proof and corrosion-proof features are required.
5. Measuring range in meters and required blind zone.
6. Operating environment: e.g., open pool, covered pool, horizontal tank, vertical tank, spherical tank, and whether the tank is at atmospheric pressure.
7. Operating voltage: 24VDC or 220VAC.
8. Output signal: 4-20mA current.
9. Device type: Integrated type
