The Manistream 111 Flowmeter is suitable for measuring the fluid
flow in open channels and pipes. It is simple to install and operate.
It does not typically require installation of a flume resulting
in significantly lower installation costs.
The Mainstream 111 Flowmeter comprises a controller with LCD display,
an ultrasonic submersible sensor used to measure speed and a pressure
transducer used to report the head of water. By calculating the
filled area in a pipe or channel and the speed of the liquid transfer
it is possible to accurately report the flow rate. The sample must
however contain suspended solids or air bubbles.
The controller can be programmed to data record the flow rate at
a pre-selectable interval form 30 seconds to 60 minutes. The memory
is sufficient for 250,000 measurements, which corresponds to 6 months
of data at a 2-minute interval. PC Windows compatible software is
included allowing simple data retrieval and also configuration of
the system including channel profiling.
Four opto-isolated analogue4-20mA outputs are provided along with
two programmable relays configurable for utility, limit or pulsed
outputs. Optional modem connection with Internet connectivity is
also featured.
