1、 Product Overview:
The OWLDF series explosion-proof electromagnetic flowmeter adopts the latest technology and is based on Faraday's law of electromagnetic induction, consisting of sensors and converters. Explosion proof electromagnetic flowmeter sensors are mainly composed of measuring tubes, electrodes, excitation coils, iron cores, and magnetic yoke shells. They are mainly used to measure the volumetric flow rate of conductive liquids and slurries in closed pipelines. For example, water, sewage, mud, pulp, various acids, alkalis, salt solutions, food slurries, etc. are widely used in industries such as petroleum, chemical, metallurgical, textile, food, pharmaceutical, papermaking, as well as environmental protection, municipal management, water conservancy construction, etc.
2、 Product features:
1. The measurement is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity.
2. There are no obstructing flow components or pressure loss inside the measuring tube, and the requirements for straight pipe sections are relatively low.
3. The diameter ranges from DN15 to DN3000, and there are multiple options for the lining and electrode materials of the sensor, which can measure corrosive liquids.
4. The converter adopts a novel excitation method, with low power consumption, stable zero point, high accuracy, and a flow range of up to 1500:1.
5. You can choose between one type and one type.
6. The converter adopts a 16 bit high-performance microprocessor, 2x16 LCD display, convenient parameter setting, and reliable programming.
7. Has multiple outputs: current, pulse, digital communication HART
8. The converter adopts surface mount technology SMT and has self checking and self diagnostic functions.
