Sensor:

Enclosure of converter : Aluminum alloy

The FLV converter is standard-equipped with the following out-

put functions which can be programmed through key opera-

tion.

Total pulse output:

The measured flow rate is integrated,

and upon reaching a predetermined unit

rate a single pulse is output. In the case

of a forward/reverse flowmeter, the flow

rate in each direction is independently

integrated and transmitted.

Low flow rate cutoff: arbitrarily settable

between 0 and 5m/s

The integration pulse cycle is settable in

a range of 5 pulses/second to 1 pulse

/day.

Auto multirange output:

When the flow rate largely varies bet-

ween low and high flow rates, output

can be done with large output width for

the whole flow range by adding the auto

multirange function.

Either two ranges are selectable, and

the minimum range is settable within

the measurable range. The measuring

range signal is transmitted from the DO

terminal.

Forward/reverse flow rate output:

Basic range

When the flow direction of the fluid

changes, then the flow rate can be mea-

sured in either direction by adding this

function.

When the flow of fluid reverses, mea-

surement is done at an arbitrary range

set differently from for the for ward

direction. The flow direction is discrimi-

nated by means of the LCD display and

DO terminal signal.

Ultrasonic pulses are propagated in turn between upstream

and downstream sides, and the time difference produced

according to the flow is detected whereby the flow rate is

measured.
