Insertion magnetic inductive flowmeter • Sensor without moving parts • Flowmeter with On/Off control • Application related calibration by Teach-In function • Clean in place (CIP) • FDA-compliant materials Type 8041 can be combined with… Type 8025 Insertion flowmeter or batch controller (remote version) Type 8802 ELEMENT continuous control valve systems The electromagnetic flowmeter 8041 is made up of an electronic module and a sensor consisting of PVDF or stainless steel material. It has been designed to measure a flow rate of neutral and slightly aggressive fluids with a conductivity of more than 20 µS/cm in DN06…DN400 pipes. It is fitted with a 4…20 mA output, a pulse output and a relay output. The different parameters can be set by means of 5 DIP switches, a push-button and a 10- field LED bargraph. It is available: - ith G 2" connection for the version with a w PVDF sensor - ith G 2" or clamp connection for the verw sion with a stainless steel sensor. The version with a stainless steel sensor can be used in applications with higher pressures (PN16) and higher temperatures (150 °C).

8041 Design The E-shaped magnetic system inside the sensor induces a magnetic field into the fluid, which is perpendicular to the direction of flow. Two electrodes are in galvanic contact with the liquid. Based on the Faraday law a voltage can be measured between these electrodes once a liquid (min. conductivity of 20 µS/cm) flows along the pipe. This voltage is proportional to the flow velocity. Using the K-factor for the individual pipe diameter the speed of flow is converted into volume per time. Display on PCB Terminal strip: - Power supply - 4…20 mA - Frequency output Green LED: -...

Installation The 8041 flowmeter can easily be installed into any Bürkert Insertion fitting system (S020) by just fixing the main nut. Minimum straight upstream and downstream distances must be observed. According to the pipe’s design, necessary distances can be bigger or use a flow conditioner to obtain the best accuracy. Fore more information, please refer to EN ISO 5167‑1. EN ISO 5167‑1 prescribes the straight inlet and outlet distances that must be 50 x DN 5 with when installing fittings in pipe linesxin order to complied x DN 25 DN 5 x DN achieve calm flow conditions. The most important...
