Clamp-on to a new smarter solution to thermal heat/energy metering from Micronics for significant installation savings and simple, accurate measurement from outside the pipe using ultrasonic technology flowmeters – the Micronics U1000 meter is suitable for flow metering hot water, chilled water, potable water and demineralised water.

Easy To Install Alternative To Cutting Pipes

Micronics U1000 is a fixed installation, clamp-on flowmeter that is easy to install and requires the minimum of information to be entered by the user. Unlike other clamp-on flowmeters, the U1000 transducer separation distance is factory preset to the internal diameter (ID) of the application pipe.

Micronics flow meters avoid any need to cut into water pipes allowing maintenance to heating systems without shutting down the system – Micronics U1000 and U3000 flowmeters feature integral energy calculators and data loggers. The flowmeters can be configured for pipe size reducing on-site setting up requirements.

Both the electronics and guide rail housings form an integral unit that is attached to the pipe using the supplied jubilee clamps. Power to the flowmeter is provided by an external 12 – 24V ac/dc power supply.

U1000 is intended to operate on steel pipes with ID’s in the range 48mm (2”) to 164mm (6”).

Measuring the thermal heat/energy consumption of hot (LTHW) and chilled water services to monitor, control and manage energy consumption is a key area in building services and energy management. But the installation process including system drain down, pipe cutting etc has always been a significant cost and barrier to wider application of sub-metering.

At last a solution has arrived, the Micronics U1000 clamp on flow meter from Micronics, the UK’s longest established manufacturer of clamp-on ultrasonic meters.

Building on their many years of experience and success in this area, Micronics has now developed a best value clamp-on heat/energy meter to compliment its successful U1000 clamp-on flow meter and facilitate the wider use of clamp-on ultrasonic flow measurement for water sub-metering and thermal heat/energy measurement.

The Micronics U1000 HM is a simple out of the box, onto the pipe heat/energy metering solution with no programming or specialist engineering required.

All you have to do is clamp the unit to the pipe, select the pipe size, release the sensor clamps, secure the pre-wired, clamp-on PT100 flow and return temperature sensors and connect power to the pre-wired cable provided.

How Does It Work?

Micronics U1000 is a clamp-on, ultrasonic flowmeter that uses a multiple slope transit time algorithm to provide accurate flow measurements.

Yes, it really is that simple because Micronics have listened and simple installation is a key design feature. Another cost-effective alternative to expensive in-line meter installation from Micronics with no drain down or cutting of pipes required plus dry servicing, providing minimum downtime and maximum availability.

Retrofit savings on existing heating and chilling plant are obvious, eliminating the need for expensive drain down, pipe cutting etc. The potential for saving on new build may not be so obvious because mechanical services installers are already present on site.

However, the installed savings on pipe sizes greater than 50mm within new build applications are also significant in comparison with traditional in-line metering products. And the larger the pipe-work for example in chilled water lines the greater the potential savings.

Using costs from Spons M&E the price for installing an 80mm insertion meter with maintenance bypass in steel pipe would be circa £2,000 more than the installation of an equivalent clamp-on meter.

Competitive tendering may reduce these rates but the installation saving will still be significant and coupled with the subsequent dry servicing and maximized availability,  the advantages and business case is clear, particularly for critical HVAC systems such as data centre’s or similar.

The Micronics U1000 HM is a clamp-on, transit time, ultrasonic flow meter plus PT100 temperature sensors designed to provide accurate measurement of liquid flowing within a closed pipe plus the flow and return temperature difference to calculate the heat/energy load, without the need for any mechanical parts to be inserted through the pipe wall or to protrude into the flow system.

It takes just a few minutes to install and there is no need to shut down flow or drain the system! It’s also Modbus compatible, so it can be used as a standalone meter or an integrated part of your aM&T or BEM’s system at no extra cost.

So if you need to meter the heat/energy load of hot (LTHW) or chilled water services as part of your energy management strategy or building services, for retrofit or new build applications, the U1000 HM should be a ‘must consider’ solution.

Typical applications for the Micronics U1000 clamp on flow meter include hot and chilled water metering and flow measurement, potable and process water metering and flow measurement and ultrapure water measurement.
