Sono-Trak™ Doppler Ultrasonic


The Sono-Trak™ Doppler ultrasonic flow meter is a non-invasive, ultrasonic flow metering system that uses advanced ultrasonic technology for higher-accuracy measurement. Based on the principles of the Doppler effect, it calculates flow velocity by sensing and measuring the frequency shift in motion from reflective materials within a liquid.

The Sono-Trak™ Doppler flow meter is based on advanced signal processing technology that dramatically increases the accuracy of flow rate measurement. Its accuracy ratings are typically ±2.0% of full scale as a function of flow profile, and repeatability is ±0.1% of reading.

This flow metering system uses two transducers mounted side by side, operating as ultrasonic signal transmitters and receivers. The measurement is obstructionless, and produces no associated pressure drops. With no moving parts to wear over time, the Sono-Trak™ Doppler flow meter is virtually maintenance-free, and is available in both fixed and portable units.



Reliable and Rugged

  • Automatic gain control -as flow profile changes so does the electronics signal.
  • Noise immunity to variable frequency drive (VFD)
  • User-friendly, easy-to-program display with on-screen prompting and keyboard entry.
  • Digital signal-allows for cable lengths up to 5000 ' (1524 m)
  • Available in a fixed or portable unit

Benefits:

  • Non-invasive design
  • Low-cost, simple installation
  • Fits outer diameter pipe sizes from 0.5 to 100" (13 to 2540 mm)
  • Rugged and maintenance-free-no moving parts
  • No pressure drop and no costly process shutdowns
  • Reliable and accurate flow readings-provides ±2.0% full-scale accuracy and ±0.1% repeatability

Suitable Fluids and Applications
The Sono-Trak Doppler flow meter is suitable for fluids containing suspended particles or bubbles with at least 35 parts per million (ppm) at 40 microns or larger, and a minimum of at least 0.2% density difference from liquid medium.

Some of the materials that are well suited for measuring include:

  • Agricultural Water
  • Abrasives
  • Asphalts
  • Concrete
  • Dredge flows
  • Drilling mud

  • Suspended solids

    Display Module
    A user-friendly, easy-to-read display provides continuous, real-time flow rate, velocity, and totalization measurements in user-selectable engineering units. On-screen prompting and a full-function, 32-character, dual-line, alphanumeric keypad entry make programming effortless

The display reads pulse, voltage, and analog rates, and it includes built-in high/low limit alarms, 4 to 20 mA signals, and an echo light to indicate whether the signal is producing accurate readings.

Heavy-duty, urethane-coated cables are pre-terminated to facilitate a speedy installation
Easy-to-read, blue backlit display allows for quick flowmeter set-up, featuring EMCO's patented menu-driven EZ-Logic™ user interface

Flexible

The same Sono-Trak flow meter can be installed on line sizes from 2 to 100" (50 to 2540 mm)
Plug-and-play input/output module options enable custom electronics configuration and/or field retrofits/upgrades; choose two from: pulse, analog, relay, RS-232, RS-485, BTU, and data logger
Standard, built-in infrared capability for use with optional Windows® software

The compact, NEMA 4X-rated, wall-mounted transmitter has a large, easy-to-read backlit display, which alternates between flow rate and totalized flow with corresponding, user-selectable engineering units. The four-button keypad allows for quick flow meter set-up, featuring EMCO's patented menu-driven EZ-Logic™ user interface. Additionally, the standard infrared communication port can be used with the optional Windows® compatible software package and serial interface device to access all configuration and data recording features.

With buffet-style input/output (I/O) module options, the electronics configuration is easily customized. Two I/O sockets will accept any of seven offered modules: pulse, analog, relay, RS-232, RS-485, BTU, and data logger. The modules are "plug-and-play," enabling field upgrades and/or retrofits. The RS-485 module allows single-point viewing of multiple meters in a master/slave configuration. The BTU module accepts two RTD inputs and performs energy calculations. The data logger collects up to 100,000 data points in non-volatile memory and can be removed from the transmitter under power and connected to a standard PC serial port for downloading and data analysis. Full diagnostics are accessible through the display, the standard infrared port, and the optional serial communication modules.

UniMag NFP

Overview:
The UniMag NFP partially filled magnetic flowmeter system is suitable for pipe sizes 6" - 80" (150 - 2000 mm). It consists of a patented UniMag NFP flowtube assembly and remote 4411e transmitter. The flowtube incorporates a removable UniMag mean velocity sensor mounted on the underside of the horizontal flowtube. For diameters 38" (950 mm) and greater two such sensors are used.


A level transducer is embodied in the Unimag NFP flowtube. It is 4-20mA loop powered by the 4411e transmitter. The signal is linearized in the 4411e and multiplied by the mean velocity to obtain volumetric flow.


The level measurement is accomplished by a choice of an FMU ultrasonic level transducer or FMX hydrostatic level transducer. The choice is determined by whether there is convenient access to the top of the NFP flowtube (use FMU ultrasonic) or to the bottom of the NFP flowtube (use FMX hydrostatic.) Type FMU is not available for sizes < 12" (300 mm).
