Materials and Chemical Resistance
The following materials of the sensor contact the flow:
 V4A (ground plate or pipe sensor jacket)
 PPO GF30 (sensor body)
 PEEK (sensor crystal cover)
 Polyurethane (cable sheath and glands)
 PTFE (gasket of sensor screw joint)
Sensors with the pressure measurement cell also include the following materials:

Hastelloy
®
C-276
 Viton
®
(PA/PR)
The sensors are resistant to standard domestic wastewater, dirt, and rainwater as well
as combined water from municipalities and communities. While the sensors do not
experience damage from the wastewater exiting most industrial plants, the sensors are
not resistant to all substances and mixtures.
In general, damage to the sensor may occur from chloride media
(corrodes stainless steel ground plate and sensor jacket), hydrogen
sulphide (H
2
S – risk of diffusion through cable sheath or sensor
that destroys copper wires and conductor paths), and various
organic solvents (may dissolve cable sheath and sensor body).
Individual substances may not adversely affect a sensor. However, under certain
circumstances, the combination of several of these substances could adversely affect a
sensor. Due to the unlimited number of possible combinations of substances, it is
impossible to determine the impact on a sensor from combining these substances.
