October 1, 2004 – ifm efector’s ultrasonic flow meter is designed to simultaneously monitor flow rate and detect fluid temperature of water in a variety of process control applications.The compact meter measures approximately 4” x 4” and mounts directly in pipes that are 1” in diameter or less. A four-digit numeric display provides water flow rate in gallons/minute or liters/minute; total quantity accumulated in gallons or liters; and temperature in Fahrenheit or Celsius. The meter’s pushbutton setup establishes sensor parameters to provide three different outputs: switching, pulse, or analog (4-20mA or 0-10V).The meter’s ultrasonic technology is based on the differential transit time principle – the time it takes for a sound wave to be transmitted and received. As water flows through the flow meter, internal piezoceramic sound transducers transmit and receive sound pulses which results in an accuracy of 3% of the measured flow value, making the meter extremely accurate at low flow rates.Ultrasonic flow meters are 4-wire DC units and available with measuring ranges of 0-13.2 gpm, 0-25.4 gpm, 0-50 l/m, and 0-100 l/m. List prices for the meters range from $575.00 to $595.00 (U.S.).ifm efector’s Ultrasonic Flow Meter Simultaneously Monitors Flow Rate, Total Volume and Temperature for Process Controlifm efector is one of the world’s largest manufacturers of sensors and control products for industrial control applications.
