The
INVALCO Model 505 Rate/Totalizer in its standard configuration,
is a meter- or wall mounted, battery- operated, intrinsically-safe,
self-contained design suitable for use in both Nema 4X
weather-proof and Nema 7 explosion-proof areas. Designed
primarily to operate with turbine meters, this device
is capable of working with positive displacement, coriolis,
paddle wheel, or other frequency-producing or contact-type
flowmeters.
Options exist to transmit the rate as a frequency or 4-20
mA signal and for high and low alarm contacts powered
externally.
Model
700 Batch Controller
The
INVALCO Model 700 Batch Controller is a single- or dual-stage
controller complete with volume and non-linearity correction
as well as automatic over-run compensation.
Other options include Mass Flow Indication, Quadrature
Pulse Input (bidirectional), and a 4-20 mA or a RS232/422
output.
Model
3002 Frequency to Current Converter
INVALCO's
Model 3002 two-wire transmitter is a flow rate-to-analog converter
designed to interface with external process control systems
or controllers. This unit converts the raw turbine meter pulse
train into a linear 4-20 mA output.
>
Available in an integral (meter) or remote mount Nema 7 explosion-proof
enclosures.
Model
705 Gas Flow Computer
Designed
for use with our GT Series gas turbine meters, the Model 705
Gas Flow Computer compensates for pressure and temperature changes
within the measurement stream. A backlit, two line, alphanumeric
display provides a clear indication of all parameters. Fully
programmable from the front panel, this device provides both
gross and net totals, rate, and a scaled pulse output as standard.
>
Options include a 4-20 mA retransmission of rate, high and low
flow alarms, and an RS232/422 communications output.
Model
715 Liquid Flow Computer
In
its simplest form the Model 715 Liquid Flow Computer is a panel-mounted
rate/totalizer, that will, with the proper options, correct
for volume changes caused by temperature or product density.
Additional features include mass flow using a density or temperature
input, volume correction to 60°F or 15°C for petroleum products,
and volume correction for general liquids using the Thermal
Coefficient of Expansion.
>
Options include a 4-20 mA retransmission of rate scaled pulse
outputs, high and low rate alarm relays, and an RS232/422/485
communication port.
