There’s good reason why we’ve been named one of the nation’s top paving, sealcoating, pavement repair, and striping contractors for three years in a row: we excel in providing both commercial and residential paving solutions, with over 30-years experience and a highly professional attention to detail. Not only do we offer complete high-quality pavement replacements. There’s good reason why we are the best in the Thorofare for commercial paving projects.
We also provide preventative maintenance to parking lots, increasing the pavement’s lifespan and reducing costs. Plus, we minimize disruption and can work in stages throughout the project, so that your employees, apartment tenants, delivery drivers, and customers are not inconvenienced.
There’s good reason why clients such as The Natick Mall, Staples, Walmart, Stop & Shop, and Dunkin’ Donuts, among many others, trust us to handle their commercial paving projects.
Our services include but are not limited to grading and paving, excavation of subgrade and full preparation, milling, reclaiming, patch work, installation of concrete sidewalks and patios, demolition, replacement, and installation of granite curbing and asphalt berm.
The sophistication of calibration procedures for level sensors depends on the degree of accuracy required. If the accuracy demands are not too high and a tank is relatively shallow, a simple dipstick inserted into a tank will suffice to verify the output reading of any other form of level sensor that is being used for monitoring the liquid level in the tank.
However, this only provides one calibration point. Other calibration points can only be obtained by putting more liquid into the tank or by emptying some liquid from the tank. Such variation of the liquid level may or may not be convenient. However, even if it can be done without too much disturbance to the normal use of the tank, the reading from the dipstick is of very limited accuracy because of the ambiguity in determining the exact point of contact between the dipstick and the meniscus of the liquid.
If the dipstick method is not accurate enough or is otherwise unsuitable, the alternative method of calibrating level is to use a calibration tank that has vertical sides and a flat bottom of known cross-sectional area. Tanks with both circular and rectangular bottoms are commonly used. With the level sensor in situ, measured quantities of liquid are emptied into the tank. This increases the level of liquid in the tank in steps, and each step creates a separate calibration point.
