SPACE-SAVING BY DRASTIC CUT OF PIPINGPARTS

MU-1000
MANIFOLD MINI-WHEEL FLOWMETEROUTLINE
Having integrated the technologies of widely-used mini-wheel
flowmeters, MU-1000 is the manifold type mini-wheel flowmeter
which fits in various compact devices and package units.
By reducing numbers of piping parts and installation cost drastically,
it realizes a compact space-saving flowmeter manifold system withnumbers of flowmeters.

FEATURES❑ Free configuration either flow collection or distribution:
Either flow collection from flowmeters into manifold or distribution
from manifold to flowmeters is selectable.
❑ Free combination with variations:
Flowmeters or through-plugs can be selected freely. Both flow
collection and distribution system can be integrated into one blockof manifold with a partition.
❑ Easy extension, rearrangement, and replacement:
Rearrangement and extension of system are at customers’
discretion in selecting various attachments, changing flow direction
and selection of flow divergences, etc.
❑ Four flow ranges:
0.6 to 3 L/min, 0.75 to 5 L/min, 1 to 10 L/min, 2 to 20 L/min❑ Pulse or current output:
It can be used with panel instruments for flow indication,integration, and alarms depending on electric signals.
❑ Direct monitoring of flow:
Through windows the rotation of wheel is visible. If the wheel getsdirty, it is easily disassembled for cleaning.
❑ Complying with UL:
UL61010-1 NYOK2/8❑ Complying with RoHS

plate

MU-1000 series has a tangential type flowmeter with a wheel in theflow path. The frequency of rotation of wheel where the magnet ismolded is picked up by the magnetic sensor element attachedto the exterior of main body of flow path, and it is outputted after
being converted to the flow signal in proportion to the flow rate.

Do not short-circuit the output. It might result in troubles.
In the current output type the minus terminals of power
supply and output are commonly connected.
Therefore, use red, white and black wires when youconnect 3 wire cables for the loop wiring.
Do not disconnect the minus line of 3-wire current

❋1 Flow path means the opening of inner valve of needle valve inmm. It is recommended to use it at more than 0.2 mm opening.

NOTES❑ Use this flowmeter where there is no stagnation of air around the wheel and also in the state of water filled up.
❑ When flowmeter is installed horizontally, the wheel axis must be horizontal. The flow path must be located above the wheel.
❑ Do not put a signal cable along with other power lines.
❑ Installation is to be made at the place free from the influence of external magnetic field which affects the characteristics.
❑ Install the filter at the upstream of needle valve in order to avoid dirt adherence due to the small opening of the valve. The adherence orclogging of the dirt may affect proper performance of flowmeter.
❑ Avoid the air blow. Otherwise, the wheel and shaft might be damaged.
❑ Close the valve slowly if necessary to avoid water hammer.
❑ Be careful for the cavitation which likely occurs when the downstream side is opened to the atmosphere.
❑ The needle valve used for the controlling of flow which is not adequate for tight shut-off. Install a shut-off valve for closing purpose ifnecessary.
