The TB26 conductivity cell is easily installed into process lines and vessels via the integral 3/4 in. NPT threads are submerged directly into lines and vessels via the 1/2 in. NPT back threads, or inserted into a process line or vessel through a ball valve. A ball valve provides isolation between the sensor and the process, enabling sensor insertion and removal while the line or vessel is full. This is accomplished by using an 11/2 in. standard ball valve. A compression fitting with flushing ports enables the operator to wash away any leftover process fluid after removing the sensor. The flushing ports also provide a quick and easy place to take a grab sample for calibration. Variable sensor lengths are available for all Model TB26 sensor styles. The hot-tap sensor can be used with the compression fitting and without the ball valve to provide even greater installation flexibility.
