MISURATORI CAPACITIVI IN CONTINUO Capacitive level meters CLM – 36 Capacitive level meters Riels CLM® are designed for continuous level measurement of liquids, powders and bulk-solid materials in vessels, tanks, sumps, containers, silos, etc. CLM consists of the stainless steel housing with electronic module and the measuring electrode. Type of measuring electrode is defined by kind of use and type of measured media. Sensitivity (SPAN) and initial capacity compensation (ZERO) can be fluently set. CLMs are offered in version (N) for non-hazardous environments or (Xi) version to explosive areas up to zone 0 or zone 20, high temperature performance and several types of process coupling are also available. Tutti i dati ed i contenuti di questa scheda sono di proprietà esclusiva di Riels Instruments • For continuous level measurement of liquid and bulk-solid materials • Direct mounting into containers, silos, vessels, basins, reservoirs, etc • Easy and quick connecting by connector • Continuous adjustment of initial capacity • Variants for usage in explosive areas, high temperature performance • Current (4 ... 20 mA) or voltage (0 ... 10 V) output With uncoated rod electrode for level measurement of non-conductive liquids (oils, diesel, petrol) and powder or bulk-solid materials (flour, sand, cement, plastic granulates, etc.). Max. length 5 m. With fully (FEP) coated rod electrode for level measurement of water and conductive liquids incl. wasted liquids in metallic vessels, concrete sumps, reservoirs, etc., better behaviour against aggressive media, lower adhesion to some complicated media, chemical resistance. Max. length 3 m. With uncoated rod electrode and reference tube for accurate level measurement of clean nonconductive liquids (oils, diesel, petrol). By means of reference tube the output signal does not depend on the dimensions and shapes of a vessel. Max. length 3 m. With fully FEP coated rod electrode and reference tube for accurate level measurement of conductive liquids. Main use is for measurement in plastic vessels or tanks. Impossible to use for waste and high viscosity liquids and bulk-solid materials. Max. length 3 m. With uncoated stainless steel rope electrode and uncoated weight for level measurement of bulk-solid materials (grains, sand, flour, cement, etc.). Max. length 20 m. With uncoated stainless steel rope electrode and coated dynamic anchorage for level measurement of bulk-solid materials in higher silos. Max. length 20 m. With fully coated rope electrode and coated weight (rope insulation FEP, weight insulation PTFE), for level measurement of electrically conductive and non-conductive liquids. Max. length 20 m. With two coated electrodes (rode insulation FEP, head fully PTFE), for level measurement of aggressive liquids. Performance for non-explosive areas only. Max. length 2 m. Accessories Standard – included in the level meter price Optional (see datasheets "Accessories") • 1x of seal, other seals are on request (PTFE, Al, etc.) • 1x connector socket • 1x screwdriver for adjustment (each 5 pcs) • Distance element for rods longer than 50 cm (for CLM – 36_–40) • Connector with protection class IP67 (GAN–DADE 7A) with 5 m cable (current output) • Connector with protection class IP67 (GAN–DAAE 7A) with 5 m cable (voltage output) • Steel welding fl ange ON–36x2 • Stainless steel welding flange NN–36x2 • Stainless steel fixing nut UM–36x2 • Dust-tight bushing PR–31 • Anchor welding cylinder KV–31 Safety, protections, compatibility and explosion proof Level meter CLM–36 is equipped with protection against electric shock on electrode, reverse polarity, output current overload, short circuit and short time over voltages. Electromagnetic compatibility is provided by conformity with standards: EN 55022/B, EN 61326-1, EN 61000-4-2, EN 61000-4-3, EN 61000-4-4, EN 61000-4-5, EN 61000-4-6. Explosion proof of CLM–36Xi is examined by FTZÚ-AO 210 Ostrava - Radvanice certificate No.: FTZÚ 02 ATEX 0235

Installation Level meters are designed to mounting in vertical position on the top lid of a tank or a container by means of welding flanges, stainless steel fixing nuts or Triclamp coupling. When installed into metallic wall vessel it is not necessary to ground the housing of CLM. In the case of use in concrete basins or silos it is recommended to install the CLM on metallic bracket or auxiliary metallic construction electrically connected with the liquid (water), or connected with metallic armour of silo. In the case of measuring in glass or plastic vessels by CLM without the reference...
