Holykell, founded in 2001, is a market leader in pressure, temperature, level and flow measurement technology. We've become a preferred partner for OEMs because we always strive to exceed our customers' expectations. Working together with our customers, we develop comprehensive solutions based on our high-quality measurement technology components, with the solutions ultimately being integrated in their business processes.Holykell has set itself the goal of developing innovative measurement technology that is easy to install,operate and offers maximum safety and reliability.

Holykell SP series magnetostrictive probe take advantages of Wiedeman effect，Viuary effect and ultrasonic effect of intelligence material, convert displacement information to time value which most easily to be measured with high-precision,so achieve high accuracy measuring for liquid level. Because of few mechanical parts, magnetostrictive probe have distinct features as high reliability 、easy-to-install and wide application, etc.
