Description The sensor type L21 is used to measure l emkotdr evels or interface of fluids in both open and pressurized tanks. It can also be used in applications with the formation of foam or aerosol, where contactless measurement methods fail. Body material of these level gauges is high quality stainless steel or chemically resistant materials. Local measurement is independent from external electrical supply which allows measurement of flammable, chemically corrosive and toxic substances also in very difficult conditions, such as high process s and pressures. On the customer's request indicator can be equipped with limit switches that allow remote monitoring of minimum or maximum level of liquid in the tank, control of pumps, opening or closing valves, etc. It can also be equipped with a continuous sensor with 4 20 ma current output for exact monitoring of the level in the tank remotely. Several optional digital communication protocols are available such as HART, Foundation FIELDBUS, PROFIBUS etc. There are several options of transmitters including reed chain, magnetostrictive, capacitive and radar principles. Mechanical local indication can be extended by a range of displays. All the devices are available for potentially explosive atmospheres with ATEX certificates. For easy draining (venting) there is screwed plug optionally accompanied by a valve. Local indicator is available in the following two options: Glass tube in which a level indicator moves tracking magnet Rolling magnetic rollers in the bar, changing color according to the level (white red). For extreme conditions it can be equipped with insulated tube, steam or electric heating of the measuring tube. Several insulation options are available according to the process conditions. L21 is a very complex product and there are many choices that are not published here. Please contact your local distributor or factory in case of any specific requests or questions. Product features Simple, robust and proven stainless steel design Ability to make parts in contact with the medium of PP, PVDF, PVC, Hastelloy or other materials in case of corrosive substances Stable local indication without need of power supply Pressure resistant and gas tight separation of the medium and indicators Easy installation of the accessories using the mounting rails (limit contacts, display outputs, scales) Indicators including limit switches and continuous outputs can be replaced without draining the tank Insulated, steam or electric heated options available. Interface measurement is possible as well In comparison with direct gauges it has lower risk of leaks and clearer local indication The device is approved for use in potentially explosive atmospheres of pressure vessels and boilers Device is designed and pressure tested according to the customers needs including s from 196 C up to 525 C Device is manufactured with accordance to PED 97/23/ES and corresponding standards Each device is pressure tested and verified. Calibration and strict functional tests are also performed on every device at the factory 4 of 61

Principle of operation The sensor is connected via flanges or threaded connections in a vertical position to the side of the tank, in which level or interface of the liquid should be monitored. It works on the principle of connected vessels. There is sealed bypass chamber with a float inside. Float has a built in permanent magnet and follows the level of liquid in the observed tank. Local indicator as well as additional sensors are magnetically coupled to the float. As the float changes its position, magnetic rollers follow it changing their orientation and thus the color (from white to red) indication current level directly. Similarly, shuttle follower indicates the level. If requested, device can be equipped with stainless steel scale in chosen units of length, volume, percentage etc. Local indication Float Medium Float is specifically designed, manufactured and tested for requested conditions of use. Double pole magnetic system is used to create uniform and strong 360 magnetic field. Magnetic system has a high gauss rating providing large safety zone for long term service taking in count effects of ageing of the magnets over time. Basic analogue output is based on the reed chain. Reed switches together with a network of resistors form three wire potentiometric circuit. The resistance between one pole and the wiper (here represented by the magnet in the float) is proportional to the level in the tank. Resistance is converted using the transducer to the standard analog signal 4 (0) to 20 ma for further processing, or advanced transducers can be used for digital communication such as HART, FOUNDATION FIELDBUS, PROFIBUS, Modbus, RS 485 and others. More advanced methods of position sensing include capacitive, guided radar and magnetostrictive principles. Detailed information is available upon request in separated datasheets. Similarly, it is possible to use a magnetic switch as a limit sensor to indicate the minimum, maximum or other selected position level in the tank. Permanent magnet in the float in this case activates the reed contact (or moves a cam that activates a micro switch in SPM version). Based on the rating of the switch it can be used directly to perform some desired function or the signal can be amplified or processed in the control system. This solution is fully comparable with the semiconductor sensing elements in the terms of reliability and precision. SIL 2 certificate is available for selected configurations. Reliability indicators are available upon request. 5 of 61

The electronics transmits very short electrical pulses (0.5 ns), which are linked to a one wire transmission line (measuring electrode). Measuring electrode can be created of rod or rope. The pulse propagates along the electrode in the form of electromagnetic wave toward the level surface, where it is partly reflected and the reflected component is returned to the receiving module of the electronics. The electronics measures the time of flight of electromagnetic wave and appropriately sets the value of the output signal. The method is resistant against changes in the atmosphere (pressure,, dust, steam) and to changes in medium parameters (change in dielectric constant, conductivity). Suited to continuous level measurement of various liquids, mush and bulk solid materials.

It s recommended to separate level meter from the vessel by valves Maintenance During normal operation device does not require special maintenance. Operation focuses only on checking for leaks, or contaminated liquids in measuring the periodic draining or flushing the measuring tube, or cleaning float. During this activity follow appropriate safety, fire and environmental measures. Electrical connection may only be performed by an authorized person. 55 of 61
