Introduction

• In the past, many utility providers have used

ultrasonic meters with varying results.

• First Doppler, then Transit- Time. The Doppler

technique requires partials in the water that can

reflect the signal.

• Transit-Time measures across the flow stream from

one transducer to the other.

Flexim utilizes a fully digitized

signal of 50 to 200 points

depending on transducer frequency

range, ensuring a high quality

signal.

Other manufacturers use a single digital

mark in the average of the signal. The

digital mark movers based on changing

temperature and process conditions,

creating meter drift and often falling

outside of the meters detection limits,

which leads to loss of signal.

Flexim utilizes smart digital processing where the signal is digitized many

times over the entire sinusoidal wave, leaving no margin for error.

Applications

The 5th largest utility in the nation has

issues with meters coating with magnetite.

Customer and Case

• The City of Jacksonville Florida has

extremely hard water and magnetite

coats the inside of magnetic flow meters

causing a short and meter reads low and

lower over time.

• JEA is the 5th largest utility in the Nation.

Application - Customer

Motivation

Potable water wells are monitored for depth, conductivity for salt water

intrusion and flow.

The World Class Magnetic flow meter company thought they had a

solution with their electrode cleaning circuit.

The magnetic flow meters came calibrated from the factory and worked

perfectly measuring water production wells for the first six months.

The flow meters began to drift downward after six months until they

read 50% of the actual flow after a period of one year.

When the 12 inch meters were removed from service, and the

electrodes cleaned with Vinegar, the meters once again read

accurately.

JEA has hundreds of meters and can not remove them and clean them

every six months.

Application - Measurement

Point

• A meter test was performed

between all ultrasonic

meters agains their meter

• A newly calibrated

• A newly calibrated

• A graduated tank over

• The utility tested the meter

over various flow rates

• The accuracy of the Flexim

meter was ± 0.9%

Customer Benefits

Improved system reliability.

Installation is easy.

No special equipment and no down time.

The utility no longer has to remove the magnetic

flowmeters and clean them.

The utility managers can trust the readings.

Calibration of the meters satisfies the governing

authority.

The cost does not increase with the size of the meter.

Why Flexim?• Calibration – FLEXIM provides NIST traceable calibration certificate acc. ISO9001

• Temperature Compensation - RTD in transducer to compensate for temperature changes enables FLEXIM to meet ASME MFC 5M sect.3 requirements for temperature compensation, while all others do not.

• Application Guarantee - FLEXIM provides an application guarantee on all equipment sold. If it doesn’t work, we take it back.

• Sensitivity - The ZERO sensitivity of FLEXIM’s instruments will provide unprecedented sensitivity to the extremely low flowrates.

• Very large turndown - Dynamic range (0.01ft/sec to >80 ft/sec) and Diagnostic Rich outputs (Empty Pipe detection, and Aeration)

• Low flowing conditions - Because of this digital processing, Flexim provides accurate flow metering down to .03 ft/sec. Other meters cannot accurately measure flow in that low range. This is why their accuracy statements list such higher velocities.

• Dynamic Transducer Compensation - The Flexim meter has no zero calibration and no zero drift. All competitive units have some zero drift (both at constant and changing temperatures) in the meter which is dealt with by using a deadband cutoff. This deadband hides zero drift but the drift still produces an error in the reading that can be extremely large especially under off peak or low/no flow conditions that will exist at your well site. Flexim has engineered the drift out of the transducers including even the need to calibrate zero.

• Maintenance - Flexim has developed permanent coupling pads, eliminating the need for recoupling the transducers to the pipe. Set it and forget it. There is no need to maintain the transducers once they are attached to the pipe. With other meters, re-coupling the transducers may be required as often as every 3 to 6 months. It can be quite time consuming keeping up with 30 meters over the entire facility.
