Water level measuring devices.
They measure the change in capacitance between two plates produced by changes in level.
The measurement system converts the potentiometer output to digital form and converts the results to the appropriate units of water level i e feet change.
High quality workmanship means devices are built to last.
The first product produced by solinst was the model 101 water level meter and forty years later hydrogeologists worldwide are still using it the model 101 water level meter first gained popularity among professionals in the united states for it s robust design stretch resistant tape and special markings in feet and tenths of feet.
Capacitance level sensors operate in the way that process fluids have dielectric constants significantly different to air.
They generally fall in two 2 major groups.
Water flow and level measuring devices we have proficient professionals who are efficient in combating all types of water flow and level measuring devices the offered product range is highly acknowledged for high strength attractive look corrosion resistance and long service life.
A 10 foot change in water level can be measured.
They monitor material level at a preset point which could be either a low level in order for example to avoid the danger of a pump running dry or a high level in order to avoid a spillage or leakage.
The pulley wheel circumference is 12 inches so that each full turn of the potentiometer corresponds to a one foot change in water level.
Applications tank level monitoring in chemical food water treatment power and brewery industries.
Other reviews have noted that the device can pick up erroneous signals from case joints and pipe fittings.
