The Triflex LNI 250 is designed to measure the level on the outside of a non-metallic tank without physical contact with the product. The LNI 250 incorporates the unique FTC technology (Field Time Control). This is a new innovative technology where an electric field is generated between multiple transmitting electrodes and a receiving electrode. The cycle time of the FTC level sensor changes as soon as a product intervenes this electric field. Multiple electrodes are embedded to detect the level of relative high dielectric material (εv ≥ 4). The Triflex LNI 250 transmitter does not require moving parts or product contact that may be subject to failure situations. Applications with a sensor with FTC Technology provide a more reliable and cost effective solution.
