length to be observed.
On request, the device may be supplied with the fluid connections fitted.
Warning
Danger from leaks
If flow-rates are low and pressures high, ensure that the system
is sealed to prevent incorrect metering or the operating fluid
from leaking.
• To ensure that the seal is secure, observe the operations
