How to avoid installation mistakes when working with Model 62-9 Insertion Probe Flow Meters

Thermal Instrument Model 62-9/9500P inserted into pipe

Installed Model 62-9/9500P Insertion Probe

Over the years our technicians have fielded numerous questions about meter performance and many of those solutions come back to some common installation mistakes. When it comes to Thermal Instrument Mass Flow Meters there are a couple things that you can check very easily when you experience a problem or suspect something is not 100% accurate with the measurement values. Here are a couple of suggestions from our technicians to common questions we receive.

Scenario: I know I have flow, but Flow Meter is not measuring anything.

Solution:

Check to make sure that the insertion probe flow meter is properly inserted into the line to the correct depth. With Thermal Instrument Model 62-9 insertion probes, the sensors are located on the bottom 3” section of the probe closest to the tip. Make sure that the tip of the probe is inserted to the proper depth depending upon the line size. Ideally you want that sensor right in the middle of the flow profile. Additionally, check all your connections and make sure that the meter is powered on and that the output cables are securely attached at the transmitter.

Scenario: As my flow rate increases, the meter seems to be consistently reading lower

Solution:

First, make sure that the sensors are facing into the flow stream. Thermal Instrument marks each Model 62-9 with a Flow Direction Arrow just underneath the transmitter condulet. Make sure that the arrow is facing in the same direction as the flow. Next, if you are running an application that is dirty or has particulates in the flow stream, check to make sure that the sensor area does not have a coating on the meter. Our meters are designed so that they can be removed from the line (please make sure you follow local safety regulations) and then simply wipe any buildup off of the probe that may have accumulated down at the bottom where the sensors are located.

Thermal Instrument @ SOAR SHOW 2022 – Kansas City, MO – March 22-23

Visit Thermal Instrument in Kansas City, MO at the SOAR / SWANA Show on March 22-23, 2021. Booth # 330.

Ray Young, Kevin Johnson will be there to answer any questions and present some new options available with our flow measurement instrumentation. Thermal Instrument has been providing mass flow measurement for more than 60 years, and has been actively working within the Landfill industry dating back to the 1980’s.

Thermal Instrument flow meters are an excellent option for all environmental compliance applications. We offer our Model 62-9 Insertion probe with Teflon Coated Sensor Area for larger lines where there may be a coating issue due to a dirty application.

If you are looking for a solution for smaller line size flow measurement, we offer our Model 600-9 which can become an extension of your existing pipe line, potentially eliminating any concerns with pressure loss due to our unique unobstructed flow path design.

We will have examples of both flow meter styles as well as various electronic transmitter and calibration options to review with you.

Looking forward to seeing you in KC!
