Micronics U1000MKII-HM

Contact Instrument Solutions

Overview

The U1000MKII-HM is an ultrasonic clamp-on thermal, heat/energy meter that uses ultrasound to measure flow rate and PT100 temperature sensors to measure flow and return temperatures. The U1000MKII-HM displays energy rate and totalised energy with pulse output and communication options, so it can be used as a standalone meter or as an integral part of an Automatic Monitoring & Targeting System (aM&TS) or Building Energy Management system (BEMS).

The instrument is simple to install by connecting power and entering the pipe inside diameter, adjusting the sensors and clamping-onto the pipe with no specialist skills or tools are required.

PLEASE NOTE - The U1000MKII-HM is available in several options, please contact a member of the BIS sales team to discuss your requirements.

Technical

Measurement technique Ultrasonic transit time method for flow measurement and PT100 Class B 4 wire for temperature measurement. Turn down ratio: 200:1

Heat meter standard The heat/energy calculation is designed to comply with EN1434 section 6

Accuracy +/- 1 % – 3 % of flow reading for > 0.3 m/s (1 ft/s)

Flow velocity range 0.1 m/s – 10 m/s (0.3 ft/s – 32 ft/s)

Pipe range Available in 2 option, 22 mm to 115 mm and 125 mm to 180 mm OD. Please note pipe size is dependent on pipe material and internal diameter

Water temperature range 0 °C – 85 °C (32 °F – 185 °F)

Temperature sensors Clamp-on PT100 Class B 4 wire, range 0 °C – 85 °C (32 °F – 185 °F), resolution 0.1 °C (0.18 °F). Minimum delta T is 0.3 °C

Output Pulse or frequency. Pulse for volume flow and energy in kWh (BTU). Frequency for flow rate. The pulse output can be configured as a loss of signal or low flow alarm
