II - B1 Visio 11 - BIT Vlsio Portable level and level/temperature meter The ll-Bl Visio level meter allows manual measurement of water level variations inside piezometers and various types of wells. The 11-BIT Visio model also displays temperature values. The instrument housing, made of AISI 316 stainless steel, is resistant to saline water corrosion and landfill leachate. The pressure transducer is piezoresistive, built with a four-arm bridge of 3.5 kOhm resistors. It is a relative-type transducer. The connecting cable is coated with a sheath offering excellent resistance to hydrolysis and microbial degradation, and contains a tube for barometric compensation. The device is equipped with an analog-to-digital conversion board and a two-line digital display that shows level and temperature values. TECNOPENTA S.r.l. Via G. Galilei, 7A/2 35037 TEOLO (PD) Optionally, the ll-Bl Visio can be equipped with a data logger for data storage and a Bluetooth transmitter to send the data to a personal computer or other devices.
