This time into our field of vision is, a kind of with 5m line length of the input level sensor, at present we have not yet purchased the probe, from the introduction, it is put into the liquid, the range has a variety of specifications, 1m, 2m, 3m, 4m, 5m, 6m, up to 10m. those too high specifications, I think it is completely beyond the application of our DIY, so first lock those 1-4m such as the range! . It claims to be suitable for fire tanks, reservoirs, ponds etc. The probe is completely waterproof, but how deep is it going to be put in?
The principle seems to be to measure the pressure at the depth of the water, and these products specifically mention that they are blockage proof.
In addition, they range in price from $12 to $50. We remember a previous user saying they wanted to measure the depth of their pool, which seems like a good idea.
