A pH meter is an electronic instrument used to measure the pH (acidity or alkalinity) of a liquid (though special probes are sometimes used to measure the pH of semi-solid substances). A typical pH meter consists of a special measuring probe (a glass electrode) connected to an electronic meter that measures and displays the pH reading. The probe The pH probe measures pH as the activity of hydrogen ions surrounding a thin-walled glass bulb at its tip. The probe produces a small voltage (about 0

Power lines “Power lines”‚ the surge of power‚ is a very good story to read; on the other hand‚ it’s very confusing. For illustration‚ the first parts of the story were jumbled up‚ first it talks about basketball then it jumps to him staring at a grasshopper. However‚ even though it was confusing there was some meaning; to begin with‚ when the power lines surged it caused some buzzing noise that gave John‚ the main character‚ a headache because he was trying to concentrate on playing basketball

LNG CARRIERS History The first LNG carrier Methane Pioneer (dwt 5034 tons) left the Calcasieu River on the Louisiana Gulf coast on 25 January 1959. Carrying the world’s first ocean cargo of LNG‚ it sailed to the UK where the cargo was delivered. Subsequent expansion of that trade has brought on a large expansion of the fleet to today where giant LNG ships carrying up to 266‚000 m3 are sailing worldwide. At the end of 2005‚ a total of 203 vessels have been built‚ of which 193 are still in service

This chapter discusses the answers to the objectives raised in this study. Remotely-Controlled Automatic Clothesline The current system is a clothesline presented in mechanically controlled by magnets. It uses X-10 module interfaced with the stamp to provide power to the clothesline from a remote location. It uses a phototransistor that acts as a motion sensor for clothes moving the line. In figure 1‚ it shows the software flow chart of the existing system.

DARWIN UNIVERSITY ENG243 – THE VENTURI METER AND THE ENERGY LINE 1. Introduction A Venturi meter is a device for determining the flow-rate of a fluid down a pipe. One measures the pressure difference between the venturi inlet and neck‚ and from this the flow-rate can be determined. The apparatus used on this experiment also has a number of straight tube manometers at equally spaced intervals. These will be used to determine the hydraulic grade line of the fluid as it passes through the

Q-Meter The Q meter is an instrument used to measure electrical properties of coils and capacitors. Mostly used in testing the radio frequency circuits. A Q-meter basically measures the Q (Quality Factor) of the circuit. It is also used to test the inductors‚ capacitors for their high frequency inductance‚ Q ‚ capacitance as well as ∑‚ tg δ value.

Dated: 12-04-2013 STEPS INVOLVED IN THE SELECTION FLOW METER There are well over 20 different types of flow meters‚ even if we lump the various positive-displacement flow meters together as one type. Unless the process engineer knows the pros and cons of each type‚ it can be a daunting task to properly select one. Here are just some of the factors to consider before selecting a flow meter: • Its size and measuring range of the flow meter • Chemical compatibility • Process accuracy requirements•
