GRD-30S radar water level gauge IP68 waterproof type level meter with RS485 output
Product Introduction
GRD-30S radar water level gauge is a high-precision, low-power non-contact radar level gauge designed by BEIJING GALLOP for use in surface (or pipe network) water level measurement; pulse coherent radar (PCR) Technology, compared with the traditional pulse radar level gauge has higher measurement accuracy and lower power consumption and ultra-small volume; using 60G sub-millimeter radar wave as carrier signal, with high precision, small size, energy saving, etc. It is not affected by temperature gradients, air pressure, surface water vapor, water contaminants and sediments; the optimized algorithm makes the measurement results more accurate and stable.
Product Advantage
1. Small size and weighs less than 300g
2. High precision, up to millimeter level
3. Stable measurement, independent of temperature and pressure
4. Easy installation and commissioning, maintenance free
5. Algorithm optimization to eliminate water wave effects
6. Low power design, easy to supply
Main Features
1. High-precision measurement of liquid level in millimeter level, ultra-low blind zone;
2. Self-contained wave-breaking algorithm, the data is stable, free from fluctuations in water surface and floating objects;
3. Non-contact, low power consumption, high reliability, maintenance free;
4. Anti-reverse connection and lightning protection design of power supply circuit;
5. Ultra-low power sleep mode, fast wake-up, can adapt to NB-IOT IoT applications;
6. In the non-contact mode, the sensor and the water body are not in contact and are not affected by the hydrological environment;
7. Multiple interface modes (digital/analog) for easy access to the system;
8. Multiple working modes: cycle, hibernation, automatic;
9. The weight is less than 300g, the structure is compact and compact; the installation is simple and the amount of civil works is small;
10. Micro antenna design, pulse coherent radar technology, leading technology;
11. IP68 is fully waterproof and will not be damaged when immersed in water.
