Proline Teqwave MW 300 – real-time total solids measurement from primary sludge to dewatered sludge
-
Measuring principle
Total solids measurement via microwave transmission
-
Product headline
Total solids measurement for the water and wastewater industry, with a compact, easily accessible transmitter. Supports sludge treatment processes (from primary sludge to dewatered sludge).
-
Sensor features
Polished tube – less maintenance due to reduced adhesion.
Fewer process measuring points – multivariable measurement (total solids, temperature, conductivity).
Easy installation – proven sensor construction. -
Transmitter features
Full access to process and diagnostic information – numerous, freely combinable I/Os.
Onboard load calculation – less effort needed in programming.

Field of application
The measuring device Teqwave MW 300 enhances sludge treatment in wastewater treatment plants through real-time total solids measurement using microwave transmission. This allows quicker, more efficient process optimization and fewer lab measurements. Continuous data availability improves solid-liquid separation, boosts operational safety, and enables swift response to process changes. Typical applications in sludge treatment include clarification, digestion, and dewatering.
The space-saving compact transmitter version Proline 300 is designed with a high degree of flexibility in mind, accommodating various operational and system integration needs. It provides access from one side, a remote display, and enhanced connectivity features. For easy operation and to provide additional process and device information, it comes with a built-in web server and optional integrated WLAN.
