Electromagnetic flowmeters, also known as magnetic flowmeters or magmeters, use Faraday’s Law of Electromagnetic Induction to determine the flow of liquid in a pipe. In an electromagnetic flowmeter, a magnetic field is generated and channeled into the liquid flowing through the pipe. Following Faraday’s Law, flow of a conductive liquid through the magnetic field will cause a voltage signal to be sensed by electrodes located on the flow tube walls. When the fluid moves faster, more voltage is generated. Faraday’s Law states that the voltage generated is proportional to the movement of the flowing liquid. The electronic transmitter processes the voltage signal to determine liquid flow.
In contrast with many other flowmeter technologies, electromagnetic flowmeter technology produces signals that are linear with flow. As such, the turndown associated with magnetic flowmeters can approach 20:1 or better without sacrificing accuracy. Continue reading “How Electromagnetic Flowmeters Work”
Since the 1950’s, the pneumatic air seeder/planter has been used as the most efficient, reliable, and cost-effective method of planting a variety of seeds. Moreover, having accurate and dependable controls are a key component to running the correct vacuum pressure for these seeding machines. Here’s how it works: using a high capacity fan, a vacuum is created in the central distribution chamber. The seeds and/or fertilizer are then pulled behind the grain drill in a separate cart. The vacuum carries the seed through tubes located under the hoppers. Seed and fertilizer are then carried in the vacuum air stream to row openers on the drill and then into the soil.

There’s a saying: “An ounce of prevention is worth a pound of cure,” and this is no different with your sensors and controls of the greenhouse/indoor farming equipment that you use and rely upon everyday. Similar to any controlled environment, it is vital to monitor and proactively interpret the pressure, temperature, relative humidity, carbon dioxide (CO2) supplementation, and irrigation of your growing space. Losing control of your environment can lead to cultivation headaches ranging from poor air flow to extreme temperatures; additionally, high humidity and low irrigation rates can lead to the spread of disease and viruses.
