The subject of our offer is a Palmer Bowlus flume intended for measuring momentary and total flow of the liquid in gravitational channels, with the use of an ultrasonic FLOWBOX flow meter. Upon request, it’s also possible to carry out pre-investment technical consulting, as well as subsequent installation, launching* and protocol-based delivery of flow meter for the use. We also sell individual elements of the measuring set manufactured by us (e.g. only Palmer-Bowlus flume or only flow meter FLOWBOX).
The liquid flow rate measurement with Palmer-Bowlus flume and water rise method in circular channels is based on the actual liquid level measured by the ultrasonic sensor (radar sensor, optional) at the hydraulic structure converted into the value of flow ratio by the measuring transmitter.
The basic condition to apply the method is to provide, undisturbed and laminar flow in a measuring flume and free outflow of liquid from the measuring flume.
Palmer - Bowlus flume, in accordance with ISO 4359:1983 "Liquid flow measurement in open channels. Rectangular, trapezoidal and U-shaped flumes” is one of the metering flumes intended for flow measurement in ducts with gravity flow. It is recommended for circular channels with gravity flow and unpressurized lines. The flume provides a close relation between liquid level and flow rate in a duct or a pipeline.
We also offer Palmer-Bowlus flumes in specialised versions dedicated to various applications.
