Ultraflo 2000 is a "Transit Time" ultrasonic flow meter designed
to work with clamp-on transducers, enabling accurate measurement of liquid
flowing within a closed pipe, without the need for any mechanical parts
to be inserted through the pipe wall and into the flow system. The Ultraflo
2000 is therefore simple to install requiring no shut downtime, with the
added advantage of no pressure drop or contact with the process liquid.
The Ultraflo 2000 has been designed for permanent metering on a pipe range of 13mm up to 5000mm and is supplied with transducers and mounting hardware to suit the application. The Ultraflo displays volumetric flow rate in a wide range of units, linear flow rate in meters and feet per second with total volume flow displayed up to a maximum of 12 digits.
Additional facilities offered by the Ultraflo 2000 are a 4-20 mA flow proportional output, Pulse output or Set point, Negative flow indication and a Display/Output variable damping making the Ultraflo cope with poor and unstable flow conditions. All outputs are configured to interface with different types of data collection systems including Building Management Systems.
An optionally available version, the Ultraflo 2000HM, can be used to meter Heat or Energy. By using the Ultrasonic transducers to measure the flow and return flow and two PT100 temperature sensors to measure the flow and return temperature of the energy source, the amount of Heat/Energy used can be displayed as kW, kCal/hr, MJ/min and MJ/sec. Flow rate, Total flow and Temperature differential are also displayed. The Heatmeter version has two 4-20mA remote outputs to monitor these measurements as well as pulse output to record Total flow or Energy.
The instrument is able to work on a wide variety of pipe sizes from 13mm up to 5000mm, simply by selecting the correct transducers and attaching them to the outside of the pipewall using the hardware provided.
Operation is push button easy such that the user is only required to know the pipe dimensions and the type of pipe wall material. All other application parameters can be measured by the instrument itself.
Flow measurement principle
When ultrasound is transmitted between the two transducers X and Y, the speed at which the sound travels through the liquid is accelerated slightly by the velocity of the liquid in the pipe. When ultrasound is transmitted in the opposite direction the flow of the liquid causes the transmitted sound to decelerate.
subsequent time difference is directly proportional to the flow velocity
in the pipe. Having measured the flow velocity and knowing the pipe cross-sectional
area, the volumetric flow can easily be calculated. Micronics engineers
have developed a measurement technique which has the ability to resolve
extremely small time differences down to 25 pico seconds (25 x10 -12
Ultraflo 2000 will be measure the flow of clean and dirty liquids in full
pipes and has a velocity of 0.2m/sec to 12m/sec. The flow range of the
meter is dependant on the pipe size and the liquid velocity which determines
the selection of transducers that are supplied with each instrument. the

Heatmeter has been designed for general purpose energy monitoring using
clamp-on flow and temperature transducers. The Heatmeter combines a flow
measurement generated by using ultrasonic “Time of Flight” technique to
measure flow with the temperature differential input generated by a pair
of PT100 temperature transducers, the combined output produces a
