Product Details

Brief Introduction:

BBZ -LD Series electromagnetic flowmeter is suitable for measuring the volume flow of conductive medium, measuring principle is based on Faraday's Electromagnetic Induction Law. BBZ-LD series electromagnetic flowmeter is mainly composed of the measuring tube, electrodes, excitation coil, iron core and magnetic yoke shell, mainly used to measure the conductivity of liquid and slurry volume flow in closed conduits, including acids, bases, salts and other corrosive liquids. The product is widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, paper and other industries as well as environmental protection, municipal administration, water conservancy construction.

Features:

Not affected by fluid density, viscosity, temperature, pressure and electrical conductivity changes;

No impeded flow parts and pressure drop in the measuring tube, lower requirements for the section of straight pipe;

Series nominal diameter of DN25 ~ DN3000, various options for sensor lining and electrode materials;

The converter using a novel excitation mode, low power consumption, zero stability, high accuracy,flow range of up to 1500: 1;

Integrated or separated for sensor and converter;

The converter using16-bit high-performance microprocessors, 2x16LCD display, convenient parameter setting, reliable programming;

Bidirectional flow meter measurement system, built-in three Totalizer for forward total, reverse total and the total amount of the difference; display two-way flow rate with a variety of outputs (current, pulse and digital, HART communication );

The converter using surface mount technology (SMT), a self-test and self-diagnostic function;
