SPECIFICATIONS

Temperature sensors with heat/energy meter UF3300.

The enhanced data logger records energy and flow, all with data indication.

Measurement technique: Ultrasound, cross-correlation transit time method for flow measurement and 4-wire PT100 Class B for temperature measurement.

Heat Meter Standard: Heat/energy calculation is designed to comply with section 6 of EN1434.

Temperature sensor: 4-wire clamp-on PT100 Class B, range 0°C – 200°C (32°F – 392°F), resolution 0.1°C (0.18°F). Minimum delta T is 0.3°C.

Enclosure: The UF3300 enclosure has an IP65 rating.

Transducers 'A': Pipes with outer diameter from 13 mm to 115 mm, IP54 with IP68 option.

Transducers 'B': Pipes with outer diameter from 50 mm to 2000 mm, IP54 with IP68 option.

Transducer operating temperature: 'A' and 'B' from -20°C to +135°C. 'A' and 'B' optional high temperature from -20°C to +200°C.

Flow range: 0.1 m/sec to 20 m/sec bidirectional.

Turn-down ratio: 100:1.

Accuracy: from +/- 0.5% to +/- 3% depending on pipe size for flow rates > 0.2 m/s.

Data communications: USB, supports most USB 2.0 BOM units.

3 x Pulse output: pulse or frequency. Optoisolated MOSFET relay.

Maximum current: 150 mA. Isolation: >100 V AC/DC. Pulse for volume flow and alarms, frequency for flow and power. Pulse outputs can be configured including:

flow totals, energy, signal loss, low flow alarms.

Volumetric mode: Pulse repetition frequency: up to 50 pulses/sec (depending on pulse width).

Frequency mode: Maximum pulse frequency: 200 Hz.

Flow rate at maximum frequency: user selectable.

4-20 mA output: 4-20 mA flow proportional output, optically isolated 1500 volts,
