This 1.5 inch inline meter supports a wide flow range (10.5–74 GPM) and uses a digital LCD to display real-time flow, totals, and instantaneous flow. It is best for mid-to-large scale fuel lines, offering robust performance in sheltered environments. Caution: Not waterproof; keep away from rain, moisture, and immersion.

Buying Guide

What to consider when choosing a digital liquid flow meter:

  • Flow range and pipe size: Select a meter that matches your pipeline diameter and expected flow rate for accurate measurements.
  • Environment: Determine if the meter will be outdoors or indoors, and whether waterproofing or EMI protection is necessary.
  • Units and display: Ensure the meter supports preferred units (GAL, QTS, PTS, L) and has a clear LCD readout for quick verification.
  • Power and maintenance: Check battery life, auto-off features, and ease of battery replacement to minimize downtime.
  • Data handling: Consider whether you need real-time display, totals, and instantaneous flow, as well as easy integration with reporting systems.

FAQ

  1. Q: Do these meters work with all liquids? A: They are designed for a variety of liquids, including water, fuels, and some oils. Verify compatibility with your specific liquid and viscosity before installation.
