ZFM Intelligent Mass Flow Meters
Aalborg Instruments (Orangeburg, NY) has
announced the ZFM Mass Flow Meters, which are
designed for multi-gas/multi-range functionality up to
8 bar (currently 6 gases) and standard accuracy of
± (0.5% RD + 0.2% FS) based on actual calibra-
tion. By connecting the instrument to the RS232/
RS485 port of a PC or laptop and running free
“ZFM Configuration Utility” software, the user can
select different gas types and flow ranges within a
few minutes without removing the instrument from
the installation. Features include:
Self-diagnostics with status LED or OLED
Automatic sensor zero offset adjustment (digital
interface or local push button).
A digital interface (RS-232 or RS-485) test/con-
figuration port (optional Modbus RTU
with isolated RS-485 transceiver).
2 programmable totalizers.
Full scale covered flow rang-
es from 3. 5 to 10 sl/min in 7
Selectable analog 0-5 VDC,
0-10 VDC, or 4-20 mA out-
Universal 14-24 VDC power
AMA & DMA MEMS Accelerometers
Jewell Instruments (Manchester, NH) has
announced the AMA and DMA series MEMS
(Micro Electro-Mechanical Systems) accelerom-
eters. Features include:
A chip-based technology, consisting of a sus-
pended mass between two capacitive plates, to
cover a range of movement (+/-1 to +/-40 g).
0-5 VDC and 4-20 mA analog outputs (AMA
RS232 and RS485 digital outputs (DMA
Availability in single, dual, and tri-axis.
Ultrasonic Distance Sensor
Hoffmann + Krippner (Woodstock,
GA) has announced P49, a
compact line of ultrason-
ic distance sensors from
PIL. P49 is a solution for
distance measurement in
applications where fast activation is essential. Features include:
Availability in 3 housing models (M18, M30, and cubic 80 x 80 mm).
Measurement distance ranges from 30 to 6000 mm.
Analog output (0-10 V), output with fixed characteristics, and models
with switching output.
Sensors that meet IP67 and are suitable for ambient temperatures
from - 20° to +70°C.
