The paddle wheel flowmeter is especially designed for use with neutral, slightly aggressive, solid free liquids. The flowmeter Type 8030/8030-HT is made up of a compact sensor-fitting (Type S030/S030‑HT) and a transmitter (Type SE30/SE30‑HT) quickly and easily connected together by a bayonet catch. The Bürkert designed sensor-fitting system ensures simple installation of the device into all pipelines from DN 06…DN 65. The flowmeter produces a frequency signal, proportional to the flow velocity, which can be transmitted and processed by a Bürkert transmitter/controller. In-Line Flow Sensor with Pulse Output Sensor Bodies from 6 mm N.B through to 50 mm N.B. Suitable for most water like fluids / chemicals Stainless Steel, Brass, PVC, PP and PVDF Sensor Materials Frequency Pulse Output, PNP or NPN; 12-30 VDC
