This instrument is widely applied by the various sewage discharging enterprises for online monitoring on the sewage discharges. The transducer will not contact with the liquid, so it will be Dirt Resistant and Corrosion Proof. This meter is stability and low maintenance, widely applied by the various sewage discharging enterprises for online monitoring on the sewage discharges, and is the best choice by the bureaus of environment protection at all levels and the sewage discharging enterprises to meter and manage the sewage discharges.
