1. Description of flowmeter composition system
Fischer porter has advanced production technology of electromagnetic flowmeter, and its products have been widely used for accurate measurement in sewage, pulp, slurry, pulp and other industries.
DM series electromagnetic flowmeter is mainly used to detect pulp, coal water slurry, slurry, cement slurry (including fine particles), mortar and other high viscosity homogeneous media, as well as liquids that generate noise due to physical or electrochemical reactions or media with the influence of magnetic fields around.

3. Technical characteristics and performance of flowmeter
(1). DM series intelligent electromagnetic flowmeter is intelligent, which is embodied in:
● the converter is equipped with a digital microprocessor, and each function menu is programmed. The flowmeter program, flowmeter parameters or flowmeter range can be checked or modified through the LCD.
● display and keys: backlit large screen LCD display, which can display instantaneous flow, cumulative flow, differential value and alarm display (excitation open circuit alarm, empty pipe alarm, flow over limit alarm).
● power failure: the instrument is internally designed with a non power failure clock, which can store 16 power failure records.
(2). The liquid crystal display of DM series intelligent electromagnetic flowmeter can display the instantaneous flow, cumulative flow and various functional parameters of the medium.
(3). DM series intelligent electromagnetic flowmeter modifies the instrument parameters as follows:
● it can be modified by three manual keys on site
● on site, it can be modified by manual operator through HART protocol
