In today's economic climate, energy usage has become a major concern, particularly in terms of energy efficiency. The increase in energy consumption has made it extremely important for industries and end users to measure energy usage as precisely as possible, so as to avoid wastage of energy. There is good reason to use flow meters in several applications to ensure accuracy in energy measurement.    In this article, we will discuss this issue in connection with chilled and heated water applications. In this application, for measuring energy consumption, a temperature and flow-measuring device is installed in chilled or heated water circuits. When linked to a BTU (British Thermal Unit) meter, the data allows end users to determine how energy is used, where and how it is used, and take appropriate steps toward improvement. But how all this is done? Let us understand a little more about a BTU meter.  What is BTU Meter ?...

  What Is Draft : Draft means a difference in pressure or differential pressure. The word draft is usually used for very low-pressure differentials up to 1000 mmwc. It is measured with the help of a transducer that converts this small differential pressure to a small electrical signal. This signal, in turn, is amplified to standard values like 4 – 20 mA, 0 – 5.0 Volts, etc., and then used for display as well as control.   Applications of Draft Measurement and control: In two main applications draft measurement and control is essential. 1. HVAC Applications 2. Boiler Applications   Here we are talking about Boiler applications. Measuring and controlling the furnace draft is important for two reasons. To increase combustion efficiency To maintain safe operating conditions.   Uncontrolled draft causes poor, non-efficient operation of a furnace (poor combustion efficiency), unstable pilot flame, build-ups of highly toxic gases like carbon monoxide, soot accumulation due ...
