Piezometer is an instrument used to measure the pressure of fluids or ground water at a specific point. Vibrating Wire piezometers use a gland and a vibrating wire sensors to measure this pore pressure. The primary use of a piezometer is to determine the pressure of ground water at a particular point or any other fluids such as, for instance, in a digging well of an extraction plant. Since the equipment gives the instant pressure and allows the data to be logged over time, it is helpful in monitoring the fluid pressure in many applications. Piezometer are used extensively in the geotechnical industry in determining the level of ground water. This is very helpful when monitoring the ground conditions around construction or infrastructure such as tunnels. Other applications include the use of piezometer on construction sites, for gauging the ground water pressure before digging up the ground for erecting a structure.   The instrument is highly efficient in de...

The advance mention technologies have brought in a sea change to the world of construction. The ultrasonic pulse velocity tester is one such instrument, and one of the longest established non-destructive tests for concrete. It provides a general measure of concrete quality, can be used to examine cracks depths, or locate voids, delamination and bad consolidation problems within concrete.  Most importantly, the features of this test method allow an operator to examine the concrete internal structure with no surface damage or destructive testing. Irrespective of the age of the building and size, ultrasonic pulse velocity tester accurately examines the condition of the building. There are wide spread applications for this instrument. It may be used to assess the homogeneity of materials including concrete and mortars. UPV results have acorrelation to strength and moduli of materials. A relationship has been established between UPV results and the depths of cracks pe...
