I would like to ask the experienced colleagues for any suggestions or opinions on improvements for electromagnetic flowmeters

Friend, you didn’t mention which company makes the electromagnet at your home; without that information, how can we resolve this issue?

Please specify which one. I work in procurement and would like to get in touch with you

Thank you all for your attention! Our company is Zhejiang Diyuan Instrument Co., Ltd., located at No. 106 Chunhan Road, Yiwu City, Zhejiang Province. It is a high-tech enterprise of ** level, and has established a strategic partnership with the American company Foxboro. The company has obtained IS9001 quality system certification, and its products have been granted the license for manufacturing special (pressure pipeline) equipment (TS2733132-2012) as well as the EU CE marking for pressure equipment under PED regulations. The company’s current products include: YYD electromagnetic flowmeters, YYW vortex flowmeters, YYC ultrasonic flowmeters, YYK orifice flowmeters, and YYV cone flowmeters. Among these, the YYD-FOX electromagnetic flowmeter was developed in collaboration with the American company FOXBORO; it offers domestic pricing while maintaining imported-quality standards. We hope everyone can offer us valuable suggestions so that we can do better! Thank you! Business Manager: Yu, 015825751587

I’ll help hold it up! A suggestion: Electromagnetic flowmeters generally operate at 220V; those operating at 24VDC are very rare, and such models are usually imported. In many cases, the locations where wastewater and acid are measured are quite far away, and it’s troublesome to provide dedicated power supply there. It would be best to develop models that can be powered by lithium batteries. This might affect the accuracy of the electromagnetic flowmeter, as a lower voltage results in a lower electromotive force, making measurement more difficult.

Hello Manager Yu, we have been in touch before. A suggestion: the response time of after-sales service could be faster. :handshake :handshake

Thank you for your advice. I will strive to make improvements going forward to ensure customer satisfaction!

In fact, like other flowmeters, electromagnetic flowmeters should be designed as 2-wire flowmeters operating at 24V and 4–20mA, rather than being powered separately with 220V. Additionally, it would be good to have another series of products: those powered by lithium batteries

I just want to ask, regarding the issue of unstable measurements when an electromagnetic flowmeter is installed at the pump outlet, the magnetic field has a significant impact on it.

It should be possible to carry out measurements when the pipe is not completely filled, with minimal requirements regarding the visible section; it must also be suitable for various installation locations. The key factor is stability – that’s what makes a product good. It seems that FOXBORD is more well-known for designing systems rather than flow meters, right?

I have a question: If the electrodes are dirty, it is possible to measure the voltage of the two shielding wires carrying the signal; if this voltage is greater than 1V, it indicates that the electrodes need to be cleaned. So, 1. Are the ends of the two shielding wires used for measuring the signal connected to terminals on the converter, while the other ends remain unconnected at the electrodes? 2. The two shielding wires for the measurement signal are called the internal leakage wire and the external leakage wire. Why are they named this way? 3. Why does a value greater than 1V indicate dirty electrodes? I have been thinking about this problem without any results; the key issue is that it’s not clear where the two shielding wires for the measurement signal end at the electrodes. I would appreciate your guidance. Please reply when you have time!
