To choose and set up a diesel flow meter, we need not only your process data but also your expectations for the process. We have some content covering how to size a new flow meter. You can also find several tools from different brands that can support you in this task. But we’ll get you started.

Setting up a diesel flow meter

To dig up some good options, I chose a couple of common tools. Emerson’s Toolkit needs you to download and install the software. That part sucks, but otherwise, it’s a good tool. And Endress+Hauser’s Applicator lets you size your diesel flow meter online, before installing anything.

Okay, now let’s lay out your process data:

  • Product: diesel
  • Pipe diameter: one inch
  • Communication: analog
  • Maximum process temperature: 40 degrees Celsius
  • Maximum process pressure:  six kilograms per square centimeter
  • Measuring range: zero to three cubic meters per hour

Recommended diesel flow meters by measuring principle

Based on your specifications, I recommend either an ultrasonic or a Coriolis diesel flow meter. So let’s go over the pros and cons of each.

Ultrasonic diesel flow meter

An ultrasonic or volumetric flow meter gives you better cost-benefit for diesel flow measurement. Also, it won’t create pressure loss because it doesn’t need a restriction in the tube. Based on your process data, you should get an accuracy of 0.5 percent on your one-inch pipe, plenty for your needs.

On the flip side, you can’t use an ultrasonic flow meter on a liquid with a high particle content, because that can affect the measurement. Plus, you’ll need minimum inlet and outlet runs, which may limit placement.

Coriolis diesel flow meter

Opting for a Coriolis diesel flow meter provides much better accuracy – a whopping 0.25 percent in your process – and requires no minimum inlet and outlet run. You also get volumetric flow, mass flow, density, and temperature measurements all in one device.

However, a Coriolis mass flow meter creates pressure loss, so you need to make sure your process can support that. And it costs more than the ultrasonic.


We based this study on the low-end options from Emerson and Endress+Hauser. If you want to shell out more, then you might find a device with extra options to enjoy.
