For Lanry electromagnetic flow meter, what conductivity does the measured liquid need to have?
Our standard electromagnetic flowmeter requires the conductivity of the measured medium to reach at least 5μS/cm to generate stable induced voltage signals for accurate flow calculation. We also provide a special low-conductivity customized model for weak conductive media, which can normally work...Read more -
Can the ultrasonic water meter be used in seawater?
Standard residential ultrasonic water meters for tap water cannot be directly used in seawater. Seawater contains high-concentration chloride ions that cause severe corrosion to ordinary copper, cast iron and 304 stainless steel bodies and transducers. Long-term operation will lead to rust, signa...Read more -
Can the ultrasonic water meter work properly in different water temperatures?
Yes, it can. Our ultrasonic water meter is equipped with an integrated high-precision temperature sensor and built-in temperature compensation algorithm. Water temperature changes will alter the propagation speed of ultrasonic waves, which may cause measurement errors without correction. The me...Read more -
Is the electromagnetic flow meter waterproof and outdoor usable?
Our electromagnetic flow meters support outdoor installation. The sensor protection grade reaches IP68, which is fully waterproof, dustproof, and rainproof. It can work stably in outdoor environments, open air, and even buried underground. The transmitter is IP65 waterproof, suitable for outdoor...Read more -
Can I use the flow meter without grounding rings?
It depends on the pipeline material. For metal pipelines with good conductivity, grounding rings are not mandatory if the flanges are well connected and grounded. For non-metal pipelines, insulated pipes, or pipes with lining, grounding rings are required to form a complete signal loop. Without p...Read more -
Can electromagnetic flow meters measure slurry and sewage?
Electromagnetic flow meters are highly suitable for slurry, sewage, wastewater, and sludge-containing liquids. Since the meter has no blocking parts inside the tube, it will not cause clogging. Special wear-resistant lining and anti-corrosion electrodes are available for heavy slurry, mining slur...Read more -
Does temperature affect electromagnetic flow meter accuracy?
Moderate temperature changes will not affect measurement accuracy. However, extreme high or low temperatures may influence lining and electrode performance. Excessively high temperature may soften the lining, while ultra-low temperature may cause material hardening. We provide different lining ma...Read more -
Can the flow meter be installed vertically?
Electromagnetic flow meters support both horizontal and vertical installation. For vertical installation, the liquid flow direction must be upward. Upward flow ensures the pipeline is always fully filled and avoids empty pipe errors. Downward vertical installation is not recommended, as it may ca...Read more -
How to maintain the electromagnetic flow meter for long service life?
Electromagnetic flow meters have no moving parts, so they feature low failure rate and long service life. Daily maintenance is very simple. It is only necessary to keep the electrode and inner lining clean. If the medium is sewage or slurry, clean the electrode regularly to prevent scaling and di...Read more -
What are the correct installation requirements for an electromagnetic flow meter?
Correct installation directly decides measurement accuracy. There are three key rules customers must follow. First, the pipeline must always be full of liquid during operation. Half-full pipe will cause no reading or wrong reading. Second, keep enough straight pipe sections: 5D straight pipe upst...Read more -
Why does the flow meter show a value even when the pipe is static?
This situation is called zero drift, which is very normal for field instruments. It is usually caused by electrode dirt, tiny temperature changes or weak external interference. The solution is simple and safe: close the valve completely, make sure the pipe is full of liquid and the flow is static...Read more -
Can electromagnetic flow meters measure air, gas or oil?
Many customers ask about applicable media. Electromagnetic flow meters work based on liquid conductivity, so they only measure conductive liquids. Standard measurable media include water, wastewater, sewage, chemical liquid, slurry, and salt water. They cannot measure gas, air, steam, pure water,...Read more
