SGM Lektra Products
LEVEL measurement and control
LEVEL GAUGES - ULTRASONIC
It is a measuring principle that works without contact with the product to be measured.
The sensor sends out short ultrasonic pulses that are reflected from the product surface and again picked up by the sensor. From the exact measurement of the time between pulse emission and echo reception, the distance to the surface and consequently the level measurement is derived. An internal digital temperature sensor corrects the measurement according to the air temperature.
Our ultrasonic level transmitters are suitable for measurements on liquids and granulates for distances up to 10 meters.
Concentrated acids, toxic wastes, vapors, presence of agitators, and measurements in by-pass tubes are no obstacles to their application thanks to an advanced signal processing system and sophisticated analysis of the received echo.
Depending on the applications are available:
- IP68 transmitters, PTU series up to 12 m
- IP67 compact units with removable display METER series up to 10 m
- IP66 compact units with remote display for KTU series calibration up to 10 m

🇮 LEVEL GAUGES - RADAR
SOLE ITALIAN MANUFACTURER
The instrument's antenna sends very narrow electromagnetic pulses in the 26 GHz baseband (K-band).
These pulses are radiated by the antenna and then reflected off the surface of the product to be measured and picked up again by the same antenna. A time-extension method allows the evaluation of the time of flight, which by its nature is particularly short, so that the distance and thus the level of the product to be measured can be accurately calculated. Dusts, vapors, high temperatures and pressures are well tolerated, allowing the units to be used in heavy-duty applications. An advanced echo curve processing system and the ability to map false echoes enable optimized measurements even under critical conditions. Thanks to the two-wire (2-wire) technique and HART communication, it is particularly easy to connect and operate the units.
The instrument antenna sends electromagnetic chirp pulses in the W-band.
These waves are radiated by the antenna and then reflected off the surface of the product to be measured and picked up again by the same antenna. The FMCW method combined with furier transforms makes it possible to accurately calculate the distance and thus the level of the product to be measured. The W-band, with a frequency sweep of electromagnetic waves in the region of 80GHz, allows the surface detection of products whose dielectric constant is low.

LEVEL METERS - CAPACITIVE
The capacitive principle for continuous level measurement is one of the most widely used in industry. Because of its adaptability, it can be applied for measurements on liquids, granulated solids, and powders. Operation is based on sensing the capacitance of the insulator interposed between the electrode and the material to be measured. The system can be compact (electrode and insert) in a single unit or separate with the insert remotely attached for reasons of high product temperature, high plant vibration, or practicality of use. The type of electrode chosen determines the unit model (CLT4, CLT8,...).
A capacitive electronic insert mounted inside a protective case determines the type of probe operation, namely:
- level transmitter, 4 to 20 mA (TC22 to 25)
- level transmitter, 4 to 20 mA + limit relay (TC26 to 29)
- level transmitter, 4 to 20 mA 2 wires (TC30)
The fully digital operation allows calibration by means of two pushbuttons or through a PC-installable s/w.

- Radar level transmitter
- Continuous contact level measurement for liquids and solids
- Max rod length 3 m ; rope 30 m; semi-flexible tube 30 m
- TDR microwave pulses
- Alphanumeric display of level measurement and echo signal curve
Features:
A short electromagnetic pulse propagates along the rope and is reflected back once it reaches the end of the rope. If the rope is immersed in the product to be measured, an echo is generated in the area of insertion into the product by discontinuity that returns toward the probe itself and is detected as the surface of the product. A time elongation method allows the evaluation of the time of flight, which by its nature is particularly short, so that the distance and thus the level of the product to be measured can be accurately calculated. Particularly suitable for powders, granulates and lumped materials such as: plastic chips in high and narrow silos, in the food industry since new calibrations are not needed by changing the type of product, with building materials such as sands, gravels, etc... Calibrations are possible even in the absence of product. The instrument inputs high-frequency pulses through a probe. The pulses are reflected from the product surface, detected by the microprocessor electronic unit and converted into level measurement. The measurement technique, combined with the EchoDiscovery management system, allows RWL units to be used even under particularly harsh process conditions. The versatility of RWL transmitters allows their application in a variety of process types with the most severe conditions such as: high temperature, high pressure, low dielectric constant, etc. with materials such as cement, sands and others.

FLOW METERS
FLOW METERS - ELECTROMAGNETIC
SGM LEKTRA has long dedicated activities in the field of flow measurement. With reference to magnetic induction flowmeters, the only requirement is that the liquid to be measured must have a minimum electrical conductivity.Magnetic induction flowmeters can be used, in all industries for measuring the flow rate of liquids in pipes from DN10 up to DN2000.
Depending on the type of application SGM LEKTRA has made 3 different product lines:

Calibration of units is performed individually on internationally certified bench in compliance with European standards.
The relevant calibration certificate, an integral part of the delivery of these instruments, has international validity.
Calibration (wet) is performed on a system with accuracy better than 99.97%. The accuracy of the calibration system is certified and checked by the N.I.M. (National lnstitute of Metrology) metrology bureau. The N.I.M. institute, a third-party entity, is internationally recognized by the B.I.P.M.
