Non contact ultrasonic level transmitter
Model: LU
Manufacturer: TECFLUID(ITALIA)
Introduction:
A transducer sends short ultrasonic pulses to a product surface. The reflection of these pulses is received back by the same transducer.
The ultrasonic waves travel at the speed of sound. The time passed since the emission of the signal until it is reflected on the product surface (T1) plus the time necessary to receive the signal back on the transducer (T2) determines the distance between the sensor and the product.
The calculation of this distance is carried out by means of a micro-processor with a powerful and smart software which selects the correct echo level among all the echos produced by the internal elements of the tanks.
A temperature sensor built-in the transducer provides the real working temperature to the micro-processor, that makes the proper calculation corrections of the measured distance.
A change in product does not affect the correct performance of the instrument, so it is not necessary to re-adjust the unit for each new product. The non-invasive level transmitter makes installation and maintenance easier.
The LU is used in:
• Level control in storage tanks of chemical and petrochemical products, treated water, waste water, rainwater,...
• Level control in storage silos of powder, granular products,...
• Level control of food products (sauces, pastry, syrup, etc.) and drinks (wine, milk, mineral water, cola drinks, etc.)
• Flow measurement in open channels, in combination with the electromagnetic sensor series FLOMAT (signal integration software not supplied)
• Control of paper, cardboard, steel and plastic reels
• Control of intermediate tanks for processes such as pumps start-stop, valve opening-closing, etc.
