INSTRUCTION MANUAL
Installation and operation of the
MODULAR DOSING SYSTEM SERIES MID- MDS
1.Application:
The Modular Dosing System MID-MDS is used on both linear and rotating filling machines, where high
accuracy/repeatability is required. The products must have a minimum conductivity of approx 1 µS/cm. The
minimum dosing time achieved to date is approx. 0.1 sec.
Magnetic Inductive Flow Meters series MID
have no moving parts, and therefore do not apply any "work" to
the product which could cause changes to the fluid structure. This also enables CIP/SIP procedures to be
carried-out both easily and quickly.
2. The dosing system MID-MDS consists of the following components (Fig.1):
- magnetic inductive flow meter series MID
with standard frequency field design, with integral pre-amplifier
- dosing control ( electronics ) series MDS:
* converter card type UV- 12
* master card type DR- 11
with integral pulse output
* counter/valve card type LS- 23
* LAUER operator terminal
* housing for card installation:
panel housing
type MDS-30 ( 30 TE ), or
panel housing
type MDS-49 ( 49 TE ), or
19" rack mounting
type MDS-84 ( 84 TE )
