The document describes the Micronics U1000 HM, an ultrasonic clamp-on heat/energy meter that measures flow rate and temperature without being installed inside the pipe. It displays energy usage data and communicates via Modbus. It is simple to install without specialist tools, lower cost than inline meters, and compatible with building energy management and automation systems.

1. The new heat/energy metering solution
from Micronics. Simple, low cost, hot
or chilled water energy measurement
from outside the pipe. A smarter
solution than in-line meters!
The U1000 HM is an ultrasonic clamp-on heat/energy meter that uses
ultrasound to measure flow rate and PT100 temperature sensors to
measure flow and return temperatures. The U1000 HM displays energy rate
and totalised energy with pulse output and Modbus communication, so it can
be used as a standalone meter or as an integral part of an aM&T or BEM’s
system.
Simple to install – clamp-on to the pipe, set the pipe diameter and connect the
power, no specialist skills or tools required and Modbus compatible.
• Rate and totalised heat/energy demand
• Easy to install
• Clamp-on flow and temperature sensors
• Lower installed cost than in-line meters

3. Clamp-on with Micronics for
major installation savings, minimal
downtime and dry servicing.
The U3000 U1000 latest generation of clamp-on,
ultrasonic flow meters from Micronics are a viable
alternative to in-line meters for HVAC metering, in
both retrofit and new build applications, delivering
major installation savings, minimal downtime,
maximised availability and significant maintenance
benefits.
Liquid flow metering including LTHW, Chilled water
and DHWS plus flow measurement for Thermal
Energy measurement are all areas where clamp-
on meters offer a best value solution for Building
Services or Energy Management i.e. they will be
significantly cheaper to install than traditional in-line
meters and as they’re non-invasive they deliver
maximum availability through dry servicing and
minimal maintenance.
The larger the pipe size the greater the installed
saving will be but with the elimination of flanges and
by-pass valves significant savings are available for a
wide range of pipe sizes with major savings for larger
applications! The following is a comparison of new
build installation costs the comparable savings for
retrofit would be higher:
Pipe Size mm –
Steel Pipe
Total cost of
installing insertion
meters with
maintenance
bypass
Cost of installing
clamp on ultrasonic
meter, half hour
labour up to 50mm,
1 hour labour from
50mm
Additional cost of
insertion meter
installation i.e.
potential savings –

be equal:

40 £601 £6.20 £595
50 £704 £6.20 £697
65 £1,681 £12.40 £1,669
80 £1,992 £12.40 £1,980
125 £3,873 £12.40 £3,860
150 £4,840 £12.40 £4,828
Insulation of clamp on and insertion meters assumed to be similar
Costs from Spons ME

The above demonstrates the potential installation price savings from
using a clamp-on solution, which would deliver an installed clamp-on
meter price with savings ranging from significant to major from 50mm
upwards. And with the added benefits of being non-invasive, requiring
only dry servicing and maximising availability.
