Hence the induced electrode voltage E is proportional to the flow velocity V of the fluid Equation 1 can also be expressed to show that the signal voltage Es is proportional to the volumetric flow rate Q Q Tr x D x V4 Equation 2 E_ B x D x K x Q 1 x D2 25 Equation 3 The application of Faraday s law for any magnetic flowmeter has a number of implications e The resulting voltage E is not dependent on the conductivity but the material flowing through the pipe must have a certain level of conductivity for the principle to work For water flow applications there is a minimum level of electrical conductivity EC below which the accuracy of the measurement will suffer Pentair flow transmitters routinely check water conductivity and can produce an alarm if the conductivity is too low The material in the pipe must cover the electrodes and in most practical applications the pipe must be full at all times for accuracy of measurement Pentair flowmeters include a pipe not full detector which is an additional connection from the flow detector to the flow transmitter The Pentair M500 Flowmeter includes electronic and digital signal processing functions to provide excellent noise reduction and signal to noise improvement M500 Operating amp Installation Manual 6 INTRODUCTION Model Numbering and Optional Accessories M500 Specification Code Details I500 Flow transmitter with DC input
