Hydroponic growers using the Nutrient Film Technique (NFT) rely on a shallow, continuously flowing stream of nutrient solution through sloped channels containing plant roots. The correct liquid level in the channel is critical: if too high, roots drown for lack of oxygen; if too low, roots dry out and nutrient uptake stops.
A typical NFT system has dozens or hundreds of channels, each needing consistent level. The NFT Channel Level Manager uses a low voltage capacitive or optical level switch at the outlet of each channel (or a single adjustable weir) to maintain a constant 2 to 5 millimeter deep film. It integrates with the recirculating pump to adjust flow rate or alerts the grower if multiple channels show abnormal level (indicating a pump problem or channel blockage). This system eliminates the most common cause of NFT crop failure: inconsistent nutrient film depth.
