Welcome to the Dakota Ultrasonics website!We are a manufacturer of industrial ultrasonic testing equipment most commonly used in the petrochemical, aerospace, automotive, and other generally related industries. The pages that follow will provide you with general information regarding our products. If you have any questions, need technical support, or have a request for custom items, please contact us at your leisure using the information provided on this site.Our products are commonly used to determine the thickness of a variety of materials by making contact with only one side of the material being tested. They have the ability to detect very fine pits, flaws, and porosity in materials without having to destroy the material or parts being tested. This is done by converting the transit time of a sound wave, sent into and reflecting back from a defect or opposite surface in the test material, into a length measurement. This technique uses principles similar to that of sonar.We also manufacture a line of ultrasonic bolting equipment that very accurately measures the stress, elongation, and load in threaded fasteners. These products are typically used in critical bolting applications where extreme accuracy is needed. If you have any specific or specialized bolting applications in mind, be sure to contact us to discuss your requirements in detail.

High Flow Range Mass Coriolis Flow Meter

High Flow Range Mass Coriolis Flow Meter Ideal for the measurement of flow, density and temperature of liquids and slurries, such as aggressive or contaminated, sanitary or particle-filled fluids.Features:

• Flow ranges from 60 to
  60K Kg/Hr (2.2 to 1650 lb/min) 
• Accuracy up to 0.25% of reading
• Materials: flow tubes -
  316 L, splitter flanges -
  316 Ti, housing - cast iron
• Process temperature
  -40°F to 356°F 
• Ambient temperature
  -40°F to 140°F
• Wide flow ranges

ACCURATE AND RELIABLEThis meter has the ability to
maintain high accuracy,
despite changing viscosity conditions, with accuracy of +0.25% of reading.

 

EASY CLEANING

The ACM series has smooth stainless steel tubes and no moving parts, and is therefore very easy to flush and clean.

 

MULTI-TASKING
The ACM series of mass coriolis flow meters measure flow, density and temperature.

 

MATERIAL COMPATIBILITY

Because of the meter's 316 stainless steel flow tubes, the ACM series can measure a wide range of materials.

 

VARIETY OF ELECTRONICS

Electronics available for the ACM series include a local, hazardous rated display and a remote, panel-mount digital display.
