Limnimetric scales provide a visual indication of water level in open-air waterways (rivers, lakes, ponds, dams, reservoirs, open channels, weirs, port docks...) withs respect to a referenced level or “zero”. The sense of the indication can be increasing or decreasing.
The scales are graduated in centimetres and marked in all decimeters (10, 20, 30, 40, 50, 60, 70, 80, 90). The lowest graduation is at the base of the scale on the positive scales and in the upper part for the negative ones. The graduations are made of cast enamel at 800 °C which guarantees extreme resistance against the action of water solar radiation. For measurements > 1 m a meter by meter marking is printed at the lower right area.
The CNC4200 is based on a ceramic die and measures the hydrostatic pressure through a capacitive effect. A vented tube inside the cable assures the compensation of the atmospheric pressure variations. It can be installed inside the water or threaded to process using its ¼” G connection (optional).
Designed to perform measurements in natural environments, the PARATRONIC´s radars are used to monitor the level of rivers, channels, water surfaces or even in pump station drains or storm water relievers.
Simple and efficient
The PARATRONIC´s CR420 or Cruzoe level sensors, are based in impulse radar technology. Its very low consumption allows a use with batteries or solar panels. Freestanding, correct automatically the falls of horizontality of 10 º. Its neutral color allows them to get confused with natural environment. The measuring cone and the reduced blind zone facilitate its involvement in confined media.
This new generation of sensor lets carry out surface water level measurements in natural environments (river, lake, pond ...) or channeled (reservoir, open channels…). They are supplied in different ranges (3, 8, 12 meters 4/20 mA or ModBus) and they can be installed by easy way in all kind of structures such as, walkways, bridges, walls, pilars
Advantages and benefits
The NRV radars are based on pulse radar technology without inmersion or contact with the effluent. The miniaturization of the case (12x12 cm sideways and 4,5 cm thick) allows a direct installation decreasing the risk of vandalism. Its protection index (IP68) is guaranteed tkanks tu its fully waterproof ABS case.
Compact and autonomous self powered solution (no power supply required), the RADIUS performs a continuous level measurement, counts and registers with time and date alarm thresholds and calculates flow rates and volumes discharged to natural environment. Data can be locally or radio remotely downloaded.
Simple and efficient
Water proof, autonomous (>5 years) and contactless operated ultrasonic sensor, thus eliminating maintenance operations, RADIUS automatically performs level measurement and logging (up to 54.000 measurements). A powerful and remotely operated software utility allows RADIUS to automatically calculate flow rate and volume values based on level measures.
Simple solution for contactless level acquisition in reservoirs, tanks, storm water spillways and weirs; locations where PARATRONIC ultrasonic sensors fit perfectly.
Simple and efficient
Easy to install (suspended from cable or fixed with an angled mounting accessory), the configuration of the US sensor can be easily set using the USP console. It provides a 2 wire 4/20 mA analog output directly or inversely proportional to level. US is supplied in ranges of 6 or 10 m with a reduced emission cone and can be connected to autonomous data acquisition systems (SCADA) thanks to its extremely reduced delay time.
Liquid level detection, alarm management and security in reservoirs, tanks, hydroelectric plants, channels, etc…, as a redundant security signal associated to continuous sensors with analog output. Suitable for raw, drinkable and rain waters. It avoids the snagging problems of traditional floating buoys and can be deployed within manholes and wells with a minimum floor area.
Static (motionless) and submersible water level switch, equipped with a magnetic float inside. Must be attached at the height where liquid level threshold detection is required. When the liquid reaches this height, it penetrates inside the outer cylinder through the Ø5 mm drills, toggling the inner float which activates a reed contact, providing a potential free contact signal.
General catalog of protectors of Paratronic
The PARATRONICs storm surges are designed to protect any electronic material (sensors, PLC, telecontrol, communication networks...) against de problems originated by overvoltages and electronic transients.
Eficient and adapted
The different PARATRONIC storm surge arresters allow tailored protection depending on the degree of exposure and the type of devices of the place to be protected. They can be supplied with or without CEM filter, with or without visual signalling and status of service contact.
