Solar Energy Ultrasonic Flow meter - ST302

ST302

For applications in rural area where electrical power is not accessible, our ST302 solar-powered ultrasonic flowmeter provides an ideal solution for accurate flow measurement. This unique product has a 20W solar panel, a 17AH re-chargeable battery, a low-power consumption GSM/GPRS modem, and a high-performance ultrasonic flowmeter. All the components, except the solar panel and transducers, are housed in a weather-proof robust enclosure.

Depending on transducer used, the ST302 product family comes as three varieties:

(1) ST302B clamp-on ultrasonic flowmeter.

(2) ST302C insertion ultrasonic flowmeter.

(3) ST302G flow-cell ultrasonic flowmeter.

All of them have better than 1% accuracy. Clamp-on version (ST302B) is non intrusive and easy to install. Insertion version (ST302C) has excellent long-term stability and better accuracy. Flow-cell version (ST302G) has the best accuracy amount the three. It is also pre-programmed in factory, thus, it is actually a play & play device.

Applications:

ST302 flowmeter is designed for remote applications where solar power is the only option to power up the system. With proper transducers, the flowmeter is able to measure liquid flow in a closed pipe accurately and reliably. Unlike traditional mechanical flowmeters, ST302 based flowmeter does not have moving parts, thus, it has long life span and need almost no maintenance. This technology measures both conductive and non-conductive liquids.

Application examples are:

• Irrigation system monitoring
• Remote pipe line monitoring
• Water, including hot water, chilled water, city water, sea water, etc.
• Sewage, waste treatment, etc.
• Oil, including crude oil, diesel oil, fuel oil, lubricating oil, etc.
• Chemicals, including alcohol, acids, etc.
• Solvents
• Beverage, food and pharmaceutical processors
• HVAC, energy measurement system, etc.
