Manual of this product.
The SLM300C/800C/990C series is a range of high quality ultrasonic level meters in explosion proof housings that provide non-contact level measurement of liquids and solids. Easy calibration and maintenance free "fit and forget" performance mean that you can install the SLM300C/800C/990C rapidly with confidence.
The SLM300C/800C/990C operates on the principle of timing the echo received from a measured pulse of sound transmitted in air and uses "state of the art" echo extraction technology.
