Water Level Indicator

Product Specifications

Technical details and manufacturing context for Water Level Indicator

Definition

The water level indicator is a component used in water tank systems to provide real-time monitoring and indication of the water level. It enables users to track tank capacity, prevent overflows, and ensure adequate water supply for various applications. The device operates by measuring hydrostatic pressure at a specific depth (for pressure-based indicators), using float mechanisms that rise and fall with the water level, or employing ultrasonic or sensor technologies to detect the water surface. The measurement is then converted into a visual display, such as a gauge, digital readout, or light indicator. The indicator is available with a measuring range of 0 to 5000 mm, with custom ranges available upon request. Accuracy is ±0.5% of full scale. The operating temperature range is -20 to 80 °C for electronics, though the sensor may differ. The supply voltage is 24 V DC ±10%, with reverse polarity protection. The output signal is 4–20 mA, two-wire loop powered. The ingress protection rating is IP65 to IP67, suitable for outdoor installation, referencing IEC 60529. Wetted parts are made of 316L stainless steel, with an optional PTFE coating, referencing ASTM A240. The process connection is G1/2 to G2 inch, depending on model, referencing DIN 3852. The weight ranges from 1.5 to 3.5 kg, depending on insertion length. Materials on file include polycarbonate, stainless steel, float (polypropylene or foam), and electronic sensors. These specifications are directory reference ranges and must be confirmed for the actual model and application with the legal manufacturer or supplier.
