The FD-7000 Series has been discontinued. Please see the FDH-1 Series as a possible alternative or contact our Flow Engineering Department.

Up to now, doppler ultrasonic flowmeters have required significant quantities of suspended particles or gas bubbles to reflect sound signals. Now, with the model FD-7000 ultrasonic flowmeter, this is no longer required. When the FD-7000 is used to measure the flow of liquids containing suspended solids or bubbles, the transducers are mounted on a straight run of pipe in the same manner as other ultrasonic meters. In applications where insufficient "reflectors" exist (a condition indicated by a low reading on the FD-7000°s flow analyzer bar graph), the transducers are relocated to a point in the piping where non-symmetrical hydraulic turbulence will be present.ideally just downstream of a 90° elbow. The FD-7000's unique digital filtering system and signal recognition circuitry transforms the reflections from this non-symmetrical, and not necessarily linear, turbulence into a useable and linear data format.

A backlit, 2 line by 20 character, alphanumeric LCD offers simultaneous flowrate and totalizer displays. The FD-7000 is designed for ease of use in the field. Only a few simple keypad entries are required to configure the flowmeter for any given pipe and flow conditions.

The encapsulated, submersible design of the transducer sensor head allows it to be easily mounted to the pipe surface with the coupling compound and elastic bands that are supplied with the unit. A 6 m (20') retractable cable for connection to the transmitter/indicator unit is supplied as as integral part of the sensor. The FD-7000 sensor is utilized on pipes that range in internal diameter from 25 mm to 1.5 m (1 to 60").

Flowrates can be measured in smaller pipes from 6 to 25 mm (¼ to 1") in diameter with use of the small pipe sensor, model FD-7000-S1.
