Flow sensor IUF

with 2 ultrasonic measuring paths for combination with calculators

for measurement of thermal energy (heating or cooling)

Nominal flow qp 15 to qp 600 m³/h

Nominal diameter DN 50 to DN 300

The flow sensors IUF serve to record the heat carrier

volume (water) in closed circulation systems of heating

or cooling plants. The scope of application reaches

from measuring points in buildings to district heating

or cooling networks .

The recorded volume can be output either in the form

of conventional volume pulses or via an optional data

interface (type VMCP / Volume Meter Cycle Protocol).

Particularly noteworthy is the compatibility with the

short case lengths of Woltman WP flow sensors, so that

these mechanical devices can now be easily replaced

by ultrasonic technology without the need for expensive reconstruction of the respective measuring point.

To complete a measuring point for thermal energy,

a calculator and a pair of temperature sensors are

required.
