Thermal Mass Flow Measurement an Effective Solution for Liquid Leachate

Thermal Instrument manufactures a mass flow meter that can accurately and dependably measure the leachate flow at landfill operations. Thermal Instrument has been measuring liquids withMass Flow Meter Measuring Leachate in 4" HDPE Pipe up to 400 GPM. Thermal Instrument Thermal Mass Flow Meter Model # 62-9 measuring leachate. Meter has protective polymer coating. mass flow meter technology for more than 50 years. We offer a tested solution for the measurement of leachate flow.  

Leachate is the liquid that naturally drains down through the landfill waste levels collecting any dissolved or suspended materials as it passes through the ground. It is a naturally occurring event that must be accounted for, captured, and treated as it is a pollutant. It is the responsibility of the landfill operator to insure that this liquid makes it to a safe holding area prior to being treated or discharged.  

A large waste and environmental service company located in Tullytown, PA, currently processes upwards of 10,000 tons of trash per day at this site. They were looking for an alternative flow measurement instrument for the leachate liquid flow.

They needed a meter that could be easily installed into a 4” SDR11 line that could measure up to 400 GPM of leachate flow. The specific location chosen is fed by 13 well heads moving leachate to a collection tank where it can be pumped out and processed.

Thermal Instrument proposed a solution utilizing their insertion probe style mass flow meter. The flow meter provides the customer with Flow and Totalized Flow information. Thermal Thermal Mass Flow Meter with Protective Polymer Coating for extra Corrosive protection or High release of passing fluid. Thermal Instrument Mass Flow Meter Model # 62-9 is available with this protective coating.Instrument is utilizing our base model 62-9 single piece insertion probe at this location. The meter has a protective polymer coating applied to the sensor area to further prevent buildup of contaminants on the probe. Notice that there are no apertures on our single piece welded insertion probe further protecting the sensors from any contamination from the passing fluid. A simple clean design that will work effectively in the dirtiest of applications for many years. The meter is easy to maintain and install and is up and runnings within minutes of installation. 

Advantages of using a Thermal Instrument Insertion Probe Flow Meter:

  • Rugged Construction – 316 SS with available protective coating

  • Easy Installation – ¾” MNPT Packing Gland

  • Installed Back up Sensors for inherent redundancy

  • Sensors are internal and never come into direct contact with passing fluid

  • Flow and Total Flow monitored

  • 4-20mA output to data recorders, PLC’s etc.

  • High Turndown Accuracy – 100:1

  • Easy to clean and maintain
