Often, domestic and hydronic systems are installed without metering devices. This is why Thermal Balance has a variety of ultrasonic flow meters in service. These meters provide a non-invasive method to measure flows within a pipe. Normal balance procedures typically do not include the use of these meters. 
Pre-testing and troubleshooting surveys are a great application for the use of these meters. Let us help you in determining flows in areas where metering devices are not available.
Please call or email us if additional information is needed. We will be glad to line up a meeting to discuss our services.
