Worldâs first parking meter installed. Share this: The worldâs first parking meter, known as Park-O-Meter No. 1, is installed on the southeast corner of what was then First Street and Robinson Avenue in Oklahoma City, Oklahoma on this day in 1935. The parking meter was the brainchild of a man named Carl C. Magee, who moved to Oklahoma City from New Mexico in 1927.
Check rate of air pressure buildup: When the engine is at operating RPM, the pressure should build from 85 to 100 psi within 45 seconds in dual air systems. (If the vehicle has larger than minimum air tanks, the buildup time can be longer and still be safe.
You can control the discharge pressure by adding a regulator on the air drive inlet. Typically the boosters outlet pressure is determined by the ratio of the booster and the air drive pressure. For example: if you are using a 2:1 ratio booster then your outlet pressure will be 2 times the air drive pressure. So if you provide a 2:1 ratio booster with 100 psi of compressed air on the air drive port, your output pressure will be 200 psi (2 x 100 = 200). How do I control flow rate? Please see our Recommended Maintenance Guide for service/maintenance inquiries. What air quality is required? If no Air Control Package is provided with the unit, then the compressed air quality must be ensured in accordance with MAXIMATOR's requirements. Requirements on compressed air quality are as follows: a. Solid matter: Maximum particle size 5 Âµm, Maximum particle concentration 5 mg/mÂ³ b.
