What media can vortex flowmeter measure?
Vortex flowmeters support three main types of medium: clean liquid, gas, saturated steam and superheated steam, with clear applicable and non-applicable scenarios as follows. Applicable liquids Clean single-phase liquid without large solid particles or viscous impurities, including tap water, cir...Read more -
What measuring principle does vortex flowmeter adopt?
Vortex flowmeters work on the Karman Vortex Street principle. A fixed bluff body (vortex generator) is installed in the center of the measuring tube. When fluid (liquid, gas or steam) flows through this obstacle, the flow is separated on both sides of the bluff body. Regular, alternating vortexes...Read more -
Can electromagnetic flowmeters be installed in a vertical position?
Vertical installation is permitted, but there is a strict requirement for the flow direction. The liquid must flow upward from bottom to top through the measuring tube. This design prevents air bubbles from gathering inside the sensor, which would otherwise lead to unstable signals and inaccurate...Read more -
Precautions for Installation of Electromagnetic Flowmeters
1. Straight Pipe Section Requirements (Critical for Measuring Accuracy) The upstream straight pipe length shall be no less than 5DN, and the downstream straight pipe no less than 2DN. If elbows, valves, pumps or tees are installed upstream of the meter, extend the upstream straight pipe to 1...Read more -
What are the advantages of using an electromagnetic flowmeter in a corrosive environment?
Electromagnetic flowmeters have prominent strengths when measuring corrosive liquids compared with other flow meters such as turbine, vortex and ultrasonic meters. First of all, there are no moving parts inside the measuring tube, which eliminates mechanical abrasion, blockage or corrosion damage...Read more -
Can the electromagnetic flowmeter be used in a corrosive environment?
Yes, our electromagnetic flowmeter can adapt to various corrosive working conditions by matching different lining and electrode materials. For mildly corrosive media such as domestic sewage and weak acid water, we adopt natural rubber or neoprene or PU, PTFE and other linings together with 316L s...Read more -
What is the difference between compact and remote version ?
We supply both integrated and split electromagnetic flowmeters to match different on-site working conditions. The integrated model combines the sensor and signal converter into one compact unit. It features lower overall cost, simple wiring and convenient installation directly on the pipeline. It...Read more -
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
