Turbine Flowmeters UGF20 Ultrasonic Gas Flowmeter -There are many reasons for choosing the UGF20 Ultrasonic Gas Flowmeter. The unit has no moving parts and requires no maintenance. As an ultrasonic gas transit time flowmeter, it does not create an obstruction in the pipe; therefore, it does not produce a pressure drop. The meter is immune to pulsation damage and impervious to particulates. The UGF20 gas flowmeter is capable of measuring over a wide flow range, eliminating the need for multiple meters. The meter is programmed at the factory in accordance with your measurement parameters. Installation simply requires mounting the sensors and connecting the power and output wire leads. Once in the field, changes to operating parameters are easily accomplished using the membrane numerical and function key pad. -The Ultrasonic Gas Flowmeter has an automatic gain control feature that compensates for the variation in signal amplitude caused by flow conditions such as pressure and flow rate. The unit also has an LCD display with LED backlight capable of displaying instantaneous flow rate, flow rate trend and total. The Ultrasonic Gas Flowmeter has multiple, configurable outputs avail-able; two 4–20 mA analog outputs, four open collector frequency outputs and one RS-422 output. This digital output eliminates errors from analog to digital conversions when the meter is interfaced with down line equipment. RS-422 allows drive capabilities of up to 4,000 feet.
