Fluidwell Non-intrusive Level Sensor

Fluidwell is a Dutch company with its headquarters located in Veghel in the south of the Netherlands. We are specialized in the development, manufacturing and marketing of electronic products and services for the process industry. Our experience and know-how in flow measurement applications, modern electronics and software, allow us to maintain our excellent and long reputation as a competent partner in solving diverse and difficult measurement problems. When it comes to industrial measuring in safe and hazardous area applications, you’ve got to have a Fluidwell.


The Triflex LNI 200 is designed to measure the level on the outside of a non-metallic tank without physical contact with the product. The LNI 200 incorporates the unique FTC technology (Field Time Control). This is a new innovative technology where an electric field is generated between a transmitting electrode and multiple receiving electrodes. The cycle time of the FTC level sensor changes as soon as a product intervenes this electric field. Multiple advanced receiver circuits are embedded to detect the level of low dielectric material, like bulk solid material or dry food products. The Triflex LNI 200 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.

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.
