- Hot Tap Installation No downtime - ideal for medium to large pipes
- Wastewater/Dirty Water Applications
Overview
PRODUCT DISCONTINUED
The ADFM Hot Tap Insertion Flow Meter is a variant of the standard ADFM open channel flow system, combining a unique sensor suitable of insertion into full, operating pipes and ADFM pulse Doppler profiling technology. It can provide accurate flow rate measurement in full and pressurised pipes with diameters of 18" (460mm) or greater, and is ideal for the difficult hydraulic conditions found in applications such as force mains, process lines and siphons.
The ADFM Hot Tap Insertion meter is constructed of robust materials which provide years of worry free operation. Installation is quick and straight-forward via an industry standard 2" tap through the wall of the pipe. This also provides easy access to the sensor for maintenance and inspection.
The Hot Tap's velocity profiling technology measures flow rate with an accuracy of +/-2% of rate, even in difficult installations such as near bends or pumps etc. The sensor uses standard ADFM electronics for data collection, processing and storage. If you are already familiar with the standard ADFM system, operating the Hot Tap system will be easy and intuitive, with all standard ADFM software, interface and communication equipment available for the ADFM Hot Tap.
