AW-Lake offers a new portable transit time ultrasonic flow meter, in addition to the full-sized clamp-on version, which provides non-contacting flow measurement for industrial environments. The new meter is designed to measure flow on demand, without installations or process interruptions.
The handheld unit is encased in a rugged IP67 housing and works with the same three interchangeable transducers as the full-sized meter for measurements on a wide range of metal and plastic pipe materials on pipes from 0.5 inches to 48 inches in diameter. A simple menu allows individuals to program the pipe diameter, pipe material, liquid types and measurement units. In addition to providing a standard 4-20mA/0-5V analog output, optional Modbus RTU and HART communications provide flow rate, volume, total, run hours and diagnostic information.
An on-screen user interface with a data logger enables operators to view flow reports or download logs for use in other programs. Data management storage of 12.5 million data points with logger software is available for data viewing and reporting. Through the use of an integrated USB-C port, the PTFM 6.1 expands its input and output capabilities to meet future requirements without replacing the whole meter.
The flow meters use the transit time ultrasonic principle of measurement that works by measuring the flight difference for ultrasonic sound pulses transmitted from one transducer to another. The time between transmitted and received signals is measured by the flow meters. These flow meters are designed for measuring the flow rate of clean, non-aerated fluids in full pipes such as water, chemicals and fuel oils.
