Daniel Model 3812 Two-Path Liquid Ultrasonic Flow Meter

A reliable and economical metering solution for non-custody transfer applications

Designed for reliable measurement, minimal maintenance and ease of operation, the 3812 Liquid Ultrasonic Flow Meter is a cost-effective metering solution for many applications in the petrochemical, oil, water and wastewater industries.

Reliable measurement

  • Operators don’t have to sacrifice accuracy for repeatability.  The 3812 Ultrasonic Flow Meter measures liquid products with a high accuracy of ±0.3% and repeatability of ±0.1% due to sophisticated algorithms and the configuration of its measuring paths
  • Innovative electronics combined with advanced digital signal processing make the 3812 less sensitive to changes in the flow profile, solids or entrained air, which results in accurate and stable measurement
  • Utilizes two mid-radius, parallel-plane measurement paths and offers a high degree of immunity to disturbed flow profiles

Minimal maintenance

  • Field replaceable transducers reduce maintenance costs and increase uptime
  • No internal moving parts to wear or drift provides for low pressure drop, increased energy savings, and maintenance-free service
  • Unobstructed flow tube with smooth surface finish inhibits material build-up

Ease of operation

  • No need for additional arrangements such as filters, flow strainers, supports, grounding or isolation against vibrations
  • Smart wireless THUM adapter allows wireless access to flow meter diagnostics without the need for any additional wiring
  • Integrated smart MeterLink diagnostics allow operators access to real-time process conditions and meter health

Cost-effective metering

The 3812 provides significant capital and operating cost savings when compared with traditional technologies such as DP meters due to:

  • High capacity and rangeability affording reduced station footprint
  • Low maintenance costs
  • One meter  for a wide spectrum of applications keeps engineering and inventory costs to a minimum
