Section 1
Integral Datalogger
All portable 1010 models include an integral datalogger that automatically logs data at selected inter-
vals. These systems use a memory management algorithm to dynamically distribute all available
system memory to the datalogger that is not in current use for site data storage. This results in a
maximum capacity of over 200 Kbytes of data (single channel, compressed). The Datalogger includes
an automatic report trigger that responds to selected real-time events. The keypad includes a “hot-key”
to generate instant datalogger reports.
Analog Outputs
The system provides all the industry standard analog outputs, which can be scaled and ranged as
required. The menu allows you to assign any available data function to an analog output. The digital
display, stripchart and datalogger screens allow local viewing of all data functions.
4 to 20 mA Outputs
z All portable 1010 models provide two independent scaleable 4 to 20 mA isolated, loop-powered,
outputs. Dual-channel models provide one current output per measurement channel.
0 to 10 Volt Outputs
z All portable 1010 models provide two independent scaleable 0 to 10 Vdc outputs. Dual-channel
models provide one voltage output per measurement channel.
0 to 5000 Hz Pulse Rate Output
z All portable 1010 models provide two 0 Hz to 5000 Hz pulse rate outputs in the form of a
buffered TTL signal similar to the final outputs of flowmeters such as turbines. Dual-channel
models provide one pulse output per channel. Pulse outputs usually represent volumetric flow.
Transit-Time Accuracy At least 1% to 2 % of indicated flow (better than 0.5 % pos-
sible with calibration.
Flow Sensitivity 0.001 fps (0.0003 m/s) - even at zero flow.
Zero Drift Stability less than 0.015 fps (0.005 m/s)
Repeatability (small volume) better than 0.5 %
Response Rate (Damping) SmartSlew effective from 0,2 seconds to 5 minutes.
Flow Velocity Range Min. ±40 ft/s (±12 m/s), inc. zero flow
Linearity 0.003 ft/s (0.001 m/s)
Flow Profile compensation Automatic Reynolds number correction of reported flow rate
1.2.3 PERFORMANCE
Under standard conditions (measurements taken on a straight run of 15 diameters upstream and 5
diameters downstream; flow rate above 1 fps; non-aerated Newtonian liquids flowing at Reynolds
numbers <2000 or >10000).
