Les transmetteurs de niveaux à ultrasons sont des instruments petite taille, servant aux mesures métrologiques et permettant d'évaluer la quantité de matière liquide présente dans un circuit d'eau par exemple. Ce type de capteur, indispensable aux industries oeuvrant à la préservation de l'environnement, fait partie des outils de mesure à distance, sans immersion et sans contact avec les liquides.
Les transmetteurs ultrasoniques peuvent être placés près des postes d'assainissement, les réservoirs et cuves de stockages, les collecteurs. On peut également s'en servir pour mesurer le niveau et le volume d'eau contenu dans les déversoirs d'orage, les canaux de rejet, voire les cours d'eau.
Cet instrument de mesure de niveau fonctionne grâce à une sonde à ultrasons qui envoie des impulsions électroniques au boîtier, qui en retour affiche les mesures et les réglages.

Vantsu ultrasonic level meter's the indicators have reached international advanced level of similar products, can fully replace others famous ultrasonic level meter. It can not only fixed point and measure continually, but also can provide the necessary telemetry, or remote control signal. Compared with radioactive level measuring technology, ultrasonic technology does not need protection; compared with the laser ranging technology, it has the advantages of simple and economic, at the same time ultrasound generally do not need the moving parts, so installation and maintenance will be more convenient. Widely used in petroleum, mining, power plants, chemical plants, water treatment plants, sewage treatment station, agricultural water, environmental monitoring, food, brewing, beverage, additives, edible oils, dairy products), flood control, flood prevention, hydrologic monitoring, open channel, space location and many other industries.
FEATURES
- The meter includes several proprietary technologies, is safe and clean, with high precision and long service life, stable and reliable, and convenient to install and maintain, and is applicable to various fields of acid, alkali, salt, anticorrosion, and high temperature.
- The meter can be connected to display meters or various DCS systems through 4~20mA or RS485 (Agreement Modbus or other custom agreements), to provide real-time level data for the operation of industrial automation.
- For circuit design, high-quality power modules are selected to be as power supply parts and highly stable and reliably imported devices are used as components of the meter. It can fully replace others famous meters of the same type.
- Patent sonic-wave intelligent technology software can make intelligentized echo analysis. It needs neither debugging nor other special steps. This technology has functions of dynamic thinking and dynamic analysis.
- Our sonic-wave intelligent patent technology greatly improves the meter’s precision, and the precision of level is up to 0.3%, which is enough to resist various interference waves.
- The meter is a non-contact one and does not directly contact , so the fault rate is low. The meter can be installed in several different ways, and the user can calibrate the meter according to the Manual.
- The meter’s all input and output lines must be with such protection functions as lightning protection and short circuit prevention.
