HYBRID ULTRASONIC FLOWMETER

Find how a Ultrasonic flow meter works on this link. Doppler technology is used to measure the flow rate of liquids with particulate and/or bubbles suspended in it. Transit time technology is used for clean liquids OMEGA’s FDH-1 Series hybrid ultrasonic flowmeter allows customers to select between doppler and transit time technology with a single instrument. Isolated analog output, frequency output and the ability to data-log to standard SD cards are standard included features. The FDH-1 is programmed via a menu driven QVGA LCD display with a 5 button interface panel. Optional control functions with relay outputs are optional (-R3). The communications option package (-COMM) gives user’s RS232, RS485, USB and Ethernet for interfacing to a PC Specifications Measuring Principle: Hybrid; user selectable doppler or transit time operating modes Fluid Types: Virtually any acoustically conductive fluid Transit Time Mode: 0 to 10% (0 to 100,000 ppm) particulate Doppler: 0.02 to 15% (200 to 150,000 ppm) 50 micron particles Fluid Velocity Range: 0.07 to 9.14 m (0.25 to 30') per second Flow Sensitivity: 0.0003 m (0.001') per second Nominal Pipe Sizes: 63 to 2500 mm (2.0 to 100") Enclosure: NEMA 4X (IP66), powder coated aluminum, SS clamps and hardware Dimensions: 279 H x 218 W x 127 mm D (11.00 x 8.60 x 5.00") Weight: 9.5 lb.

Hardware included Panel Opening: 270 H x 206 W mm (10.63 x 8.10") Panel Depth Rear: 71 mm (2.78") Front: 55 mm (2.18") Power Requirements: 95 to 264 Vac 50/60 Hz or 15 to 30 Vdc; 30 watts max Operating Temperature: -10 to 60°C (14 to 140°F) Storage: -40 to 70°C (-40 to 158°F) Display: 320 x 240 pixel QVGA backlit LCD, UV resistant. Simultaneous rate and Total; 10 digit max + exponent to E+32 decimal location configurable to 10 places Display Languages: English, Spanish, French or German selectable Keypad: Five-button positive action tactile switch keypad Security: Programmable master password and individual configuration passwords Display Volume Units: Independently configurable rate and total display units in U.S. Gallons, ounces, barrels (US liquid), barrels (US oil), cubic ft, acre ft, Imperial (British) gallons, liter, cubic meter, or user defined “custom” units. Rate display in feet or meters per second. Display Time Units: Seconds, minutes, hours, days Display/Output Response Time: Selectable; 0.25, 0.50, 1.0 (default), 2.5, 5.0 seconds Flow Rate Display Averaging: Selectable; 0.50, 1.0, 2.5, 5.0 (default), 10.0 sec Data Outputs: Isolated 4 to 20 mA output fully configurable, invertible; 0 to 1000 Hz pulse output fully configurable, invertible Data Logging: Date/time stamped flow rate and flow total data in FAT32 file format, easily imported into Excel. Configurable to trigger on time interval (1-999,999 sec), rate and/or total set-point values. Over 500,000 log events possible with included 32 MB SD card. Process Control (-R3 option): Three independently configurable 10 amp Form C, NO/NC relays. Configure to flow rate for high/low/ range rate alarm. Programmable release values enable auto release or manual latching operation. Configure to flow total for manual trigger batch operations or automatically triggered, timed batch operations External Communications (-COMM Option): Computer connection via RS232, RS485, USB, Ethernet. Includes user communication and configuration software. Permits remote internet access through local network set-up. Remotely access and upload data logging files Clamp-On Transducers Housing: NEMA 6P (IP67), Nickel plated aluminum, SS clamps and hardware Dimensions: 79 H x 75 W x 41 mm D (3.12 x 2.95 x 1.60") Weight (Excluding Cable): 0.8 lb (0.4 kg) each Cable: Shielded coaxial RG/U Type; 59. PVC jacket, black. RoHS Compliant Standard length: 3 m (10') Optional Lengths Available: 15 m (50'), 30 m (100') Pipe Surface Temperature: -34 to 121°C (-20 to 250°F) Shipping Specifications Carton Dimensions: 533 H x 432 W x 241 mm D (21 x 17 x 9.5") Carton Weight: 24 lb (10.9 kg) Note: For fluid, flow stream, minimum straight pipe and mounting requirements see the FDH-1 operator’s manual at: omega.com/manuals Communications Options Any FDH-1can be equipped with a communications package (-COMM) that includes Ethernet, USB, RS232, and RS485 connections, and proprietar user PC Software. When connected to a PC running the software, the user can access the configuration menu for program editing and data logging downloads directly into a PC. The software user interface mimics the 5-button touch pad so learning to use the software application is simple. Simply clicking on the buttons is the same as pressing the buttons on the FDH-1 touch pad. Pressing and holding shift while clicking on a button simulates pressing and holding a button on the touch pad Process Control Options Any FDH-1 model can be equipped with a process control relay package (-R3) that includes three independently programmable 10 A relays. Each relay can be configured to respond to changes in either the measured rate of flow or the accumulated total flow value. When assigned to monitor flow rate, high/low/ range rate alarms are possible. When assigned to monitor accumulated total, manual trigger batch operations or automatically triggered, timed batch (proportional feed) operations are possible.
