Scraper type electromagnetic flowmeterThe manufacturer of the production quotation for this flowmeter product model belongs toElectromagnetic FlowmeterClassification: For more direct sales price quotations of electromagnetic, scraper type, and flow control instruments, please feel free to inquire by phone. Below are the product information details of scraper type electromagnetic flow meters.

When measuring fluids that are prone to dirt and attachment, such as slurries and other media, the electrode surface is often covered with dirt, causing the instrument output to oscillate and drift. In severe cases, it is impossible to measure. At this time, the electrode needs to be cleaned,Scraper flowmeterUsing mechanical cleaning method, a stainless steel scraper with a thin shaft and a hollow electrode is made and sealed to prevent the medium from flowing out. Therefore, a mechanical scraper is formed. When the outer cover of the electrode body is opened and the thin shaft is rotated, the scraper rotates tightly against the electrode end plane to remove dirt. This scraper can be manually operated or driven by a motor to drive the thin shaft. This instrument adopts manual method, and the electromagnetic diameter of the scraper electrode starts from DN80, and the electrode is made of 316L stainless steel.

Scraper type electromagnetic flowmeterIt is also composed of converters and sensors, and is a new type of multifunctional intelligent sewage flowmeter. Adopting a large screen graphic LCD display, instantaneous flow rate, cumulative total amount, medium temperature, pressure and other parameters can be displayed simultaneously. The user-friendly Chinese operation interface and multi parameter intelligent setting bring great convenience to on-site personnel.

The control chip used has high stability, strong applicability, more accurate measurement, and can be used in conjunction with various electromagnetic flow sensors; Or button operation, in accordance with national explosion-proof design, can be applied to explosion-proof places; Process patch technology enables higher measurement accuracy of scraper flow meters; Modular board design, fast and easy maintenance and upgrade. When the power is cut off, the set parameters and accumulated values are automatically permanently stored, and the flow file is foolproof; Provide converter native self-test function. Provide multi-stage nonlinear correction and automatic zero calibration functions for sensors.
