My father, Kiryako Arvanetakis (1926–1983) was a brilliant engineer and inventor. The highest accolade I received was from the retired president of a well respected consulting firm that frequently contracted him for difficult projects. He told me that there was never a difficult problem that he didn’t solve...and brilliantly.

As a young boy I remember watching him in our garage build a cube from aluminum square tubing and string almost hair thin copper wire at two ends. He explained that NASA was planning to put a man into orbit and that one of the concerns was high speed meteorites that might damage the spacecraft. NASA was building a pneumatic gun that would fire projectiles into various sample materials at very high speeds---faster than with gunpowder---but there was no way to measure these extreme velocities. My father was contracted to find a solution.

"Breaking the first wire starts charging a capacitor" he explained to me. "Breaking the second wire stops the charge. I know the rate of charge, so measuring the accumulated voltage I can calculate the elapsed time.” As a boy of six or seven I understood nothing that he said and I am amazed that I can still remember his words. From what I can determine among his many other inventions dad designed and constructed the first electronic ballistic chronograph in the 1950’s. Today anyone can purchase one of these for almost pocket change. A light beam is broken instead of copper wire. An inexpensive microprocessor measures the time instead of a capacitor.

In the early 1980’s I represented a flow element manufacturer while continuing my studies in mechanical engineering. I remember watching the emergence of the first practical thermal mass, coriolis, vortex and ultrasonic flow meters and thinking "We’re toast!” While the new technologies certainly have replaced the old in many applications, they have equally opened up new applications that the old could never do well. Advances in microprocessor and sensor technology have allowed the original works of Bernoulli, Faraday, Coriolis, von Karman, and many others to be further practically applied with enhanced performance and often decreased cost. And there are, of course, new methodologies that perform in previously difficult or impossible applications.

Techrep distributes a wide range of flow measurement products from a number of different manufacturers, most (but not all) are listed on our line sheet. What is not listed is the experience we have in providing this equipment to virtually every industry since 1975. I like to think of our company as source of information which will allow a customer to make a series of intelligent decisions leading to the correct product. At this conclusion we hope to have positioned our company as a competitive source for this product, but if not we are glad to refer you to someone who is. In any event it would be a pleasure to serve you.
