A venturi meter measures fluid flow rate using a Herschel venturi tube. Bernoulli’s principle is used to calculate flow rate by measuring pressure before and after the venturi. The tube design reduces head pressure degradation. The formula considers pipe radius, fluid compressibility, and other variables to obtain an accurate flow rate. A venturi meter, or […]
An electric demand meter charges customers more for peak demand periods, as electricity cannot be stored. It measures the highest level of demand over a period of time and allows the company to recoup costs while maintaining affordable prices. An electric demand meter works on the principle that customers who require a higher or more […]
Track gauge is the distance between two rails on a track and is not standardized worldwide, causing inconvenience and safety issues. The standard meter of 1,435 millimeters is used by many countries, and double gauge is used in regions with different standard sizes. Model railroad enthusiasts value precision in track gauge. A track gauge is […]
Load meters are devices found in electric meters that indicate peak electricity usage. They come in two types, mechanical and electronic, with the latter transmitting a signal to utility companies. Personal load meters are available for purchase to monitor energy usage and control appliance usage more efficiently. A load meter is a device commonly found […]
An engine meter monitors engine running time for proper maintenance intervals. Different designs track specific processes, such as actual running time or RPM. Engine meters are compared to hub meters to decipher drive time versus idle time. Tampering with the meter can result in termination. Modern versions work within the vehicle’s computer system and are […]
Rules for parking at broken meters vary by location. Check with your local department of parking and transportation. Report broken meters and note that in some areas, parking at a broken meter is not allowed and can result in a ticket or towing. Some cities allow parking at broken meters for the posted time limit. […]
The Hobbs meter is an instrument used in the aviation industry to measure elapsed time for record-keeping purposes. It can be activated in various ways and is used to establish service intervals for aircraft parts and log pilot flight hours. Newer aircraft integrate time recording functions into electronic flight management software. The Hobbs meter is […]
Electromagnetic flowmeters measure liquid flow through a pipe using conductivity and a magnetic field. They are non-invasive, low maintenance, and can be used in various industries. Proper grounding is necessary for accurate readings. An electromagnetic flowmeter, also known as a magmeter, is an instrument that measures the rate of flow of a liquid – or […]
Air flow meters measure air flow through a tube, commonly used in automobiles to regulate engine ignition. They can be connected to computer systems and used for experiments. Malfunctions can occur due to blockages or damage. Cost varies based on application and accessories. Calibration is important for accuracy. An air flow meter is a device […]
Ultraviolet meters are sensitive to UV light and are used to measure personal exposure to UV rays, monitor climate trends, and confirm the effectiveness of UV sterilization systems. They can be purchased from scientific supply companies, outside suppliers, and manufacturers, and are sometimes available for free at safety seminars. UV meters come with guides suggesting […]
