Loss of electrical capacitance during measurement is an intrinsic problem that plagues conventional electrostatic capacitance. To overcome it, DITECH's Non-induction Electrostatic Capacitance Series employs innovative technology to prevent capacity losses during the measurement process both within the meter circuitry and along the non-induction extension cable between the electrodes. Thanks to this technology, these devices offer unprecedented accuracy and stability. This instrument has been designed based on a totally new measurement concept and advanced electronics to exhibit high performance as a water/fluid level transmitter used to measure the level of water and other fluids.
DITECH has a wealth of experience in conducting elaborate testing of samples and plenty of expertise in dealing with water and other liquids of various properties. We offer optimal products for the object you would like to be measured.
Every material has intrinsic electrical characteristics such as permittivity and conductivity. This transmitter detects electrostatic capacitance changes generated by the rise or fall of the level of the measured substance in the tank, and then converts these changes into an integrated signal. A variety of meters and detectors are available according to the measurement condition.
Non-induction system designed to be totally unaffected by capacitance losses
Totally electronic system with no moving parts ensures a long working life.
Wide measurement range - Min. 0 mm to Max. 100 m.
(level transmitter for deep well is also available.)
An increased degree of design freedom make it possible to adjust the electrode shape to match the measurement location conditions.
(Straight-rod probe type, Wire type and etc.)
Solid body construction designed for long-term durability and easy maintenance.
Detector and transducer can be separately installed without effecting the device's operating performance.

This model is composed of detector unit, transducer, relay power source and special cable that is 4 core control cable. As the transducer is designed to be installed in a dangerous area, the special cable can be made short enough to minimize picked-up noises, thus permitting a stable performance to be obtainable. As to performance, this model has the same characteristics as those of Model QBS-WF.
