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 temperatures 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 temperature 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.

Productfeatures

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 temperatures 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

Principleofoperation 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.

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.

B1FloatforbypasslevelindicatorL21

Floatdimensionsanddependenceonthedensity

The float type, its length and diameter are chosen according to specific media parameters and operating conditions. The float has the same serial number as magnetic level indicator. For illustration we present a table of dimensions for selected densities in the most widely used type of float (stainless steel, Ø50 mm, PN16).

Float length (mm) Medium density (kg/m3)

1010 400

515 500

213 900

191 1000

176 1100

164 1200

Changes of the operating conditions (temperature, pressure, density) causes shift of the measuring edge, depending on the density of the liquid. If we know the density we can correct it by moving the scale and sensors. Optionally it is possible the float for different densities supply with weight. Float material: Stainless steel DIN 1.4541, DIN 1.4571, titanium, PP, PVC, PTFE, full‐composite design. Materials magnetic coupling: samarium‐cobalt, neodymium‐boron. They are powerful magnetic materials. We use AlNiCo material for high temperature. Maximum float speed at which is a local indicator function is up to 1,5 m/s.

Guided wave radar level measurement

The function principle of the impulse radar (microwave) level meter is TDR (Time Domain Reflectometry). 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, temperature, 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.

Ordering

When ordering please specify:

Type of medium, concentration in %, the content of mechanical and ferromagnetic impurities

Density and viscosity

Temperature and pressure (operating and maximal)

Measurement range

Units

Requirements for the electrical outputs

Installation

Before you install the device, check that the measuring body doesn’t contain any impurities

Careful when inserting the float into its proper position, the upper part has two indentations at a

distance of 6 mm from each other

Sealing must be centered in the flanges and threads

Fittings can be tighten by torque specified for the operating pressure in the tanks

Each unit is pressure tested 1.5 times of the operating pressure, which is specified in the order, the float

is only tested 1.3 times of the pressure

Check the operating data on level meter label if that correspond to the measured liquid

Before commissioning, make sure the drain and air plugs, drain and air valves are closed

Open the shut‐off valve at the meter connecting flanges, first upper valve

Now it’s ready for measurement

Avoid pressure surges and abrupt changes in level ‐ risk of float damage

During handling with the level indicator it’s necessary to avoid abrupt changes in position so

that the float chamber due to the acceleration of gravity moved as slowly as possible in order to prevent

impact damage.

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.
