* 1) Maximum flowrate may be increased by 25% for short periods when used with low
viscosity liquids with lubricating properties.
2) Accuracy levels for the MP015 are +/-1% within nominal flow spans. Accuracy over the full
flow range is improved to within +/-0.5% when utilising the linearisation feature of the
optional Trimec RT flow rate totaliser.
Flowmeter label
The label plate identifies the flowmeter
model number, serial number,
temperature & pressure ratings.
Temperature & pressure ratings are
maximum and must not be exceeded.
Bridge solder pads when the
500Ω current limiting resistor is
not required. Maximum current
allowable is 50mA

Important:
Hall effect output supply is to be
limited to 24Vdc maximum, should it
be possible for the voltage to spike
beyond 24Vdc apply optional PR1
pulse repeater / isolator module as
shown below.
