SUBJECT OF THE OFFER
The subject of our offer is an ultrasonic flow meter FLOWBOX intended for measuring momentary and total flow of the liquid in gravitational channels, with the use of Palmer-Bowlus flume. 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).
* Launching of our ultrasonic flow meter FLOWBOX in your facility (unlike many products of the competition) is very simple and in most cases, it doesn’t require a visit of specialized service – we provide factory pre-programmed (for the given type of flume or measuring weir) and pre-calibrated set (only one parameter needs to be adjusted).
MEASURING SET DESIGN
* FLOWBOX flow meter = Ultrasonic level sensor with cable + M1600 Transmitter
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.

Set design - ZPB flumes------------
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.

SPECIALISED VERSIONS OF ZPB FLUMES
We also offer Palmer-Bowlus flumes in specialised versions dedicated to various applications: Inter alia we recommend Palmer-Bowlus flumes:
with SIDE MEASURING STACK for measurement of foamy liquid flow
with VERNIER for visual determination of current flow rate in the pipeline, without electronic measuring instruments.
in HERMETIC version (antiodor)
with additional measurement (dissolved oxygen, pH value, ORP, conductivity) of a liquid (with FLOWBOXplus flow meter)
