4 Area of application
The magnetic-inductive flow velocity sensor PITe is be used to measure or monitor the volume flow of
liquids with and without solids concentration, slurries, pastes and other electrically conductive media
while minimizing pressure drops. The conductivity of the medium must be at least 50 µS/cm. Pressure,
temperature, density and viscosity do not affect the volume measurements. Small quantities of solid
particles and small gas bubbles are also measured as part of the volume flow. A larger number of
solid particles or gas bubbles will lead to incorrect measurements. Special electrodes are available for
media that tend to form greasy films or crusts.
To perform flow measurements, the PITe sensor must be operated with a Heinrichs Messtechnik
transmitter of the UMF-x series, for example the UMF2 (B). The transmitter UMF2 (B) is a
programmable transmitter that process the measurement data received from the sensor displaying the
results on
it’s
built in control panel. Furthermore, it is capable of transmitting various types of
measurement results via a communication interface.
5 Safety aspects during commissioning and maintenance

This document contains all the necessary information to ensure a correct operation of the herein
described product. The document is intended for use by qualified personnel. This means personnel
who possess the necessary knowledge needed to ensure a safe operation of the device, such as
electronics engineers, electrical engineers, or service technicians who are conversant with the safety
regulations pertaining to the use of electrical and automated technical devices.
Such personnel must be authorized by the facility operator to install, commission and service the
product described herein. Before any work is carried out on the device, these operating instructions
must first be thoroughly read and understood.
The principle rules and regulations in the country of the operator must be observed.
5.2 Intended use of the device
Warning
The operator is responsible for ensuring that the material used in the sensor and
housing is suitable for the application, and that such material meets the
requirements for the fluid being used and the ambient site conditions. The
manufacturer accepts no responsibility when inadequate material and housing are
ordered.
Warning
To ensure a correct and safe operation of the device, it must be shipped, stored,
set up, mounted, operated and maintained correctly.
