40 years of innovation from the inventors of solid state data logging

DFR-77 DATA LOGGER1977 - The world’s first commercial EPROM data loggers, the MACE DFR-77 were delivered. Hundreds of these instruments were used throughout Australia and Papua New Guinea working under the harshest imaginable conditions. The EPROM data recording technique proved to be the most reliable method of electronic data storage.

HYDROMACE TRS1984 - MACE introduced the Hydromace system which gave environmental field stations the combined capabilities of data logging, control, telemetry via telephone, radio or satellite and intelligent response to both computer or human interrogation.

HYDROMACE 20001992 - The HydroMace 2000 data logger provided multi-channel logging and control in water catchments, sewer treatment plants and industrial pollution applications. A leader in its time, many are still in use in catchment management and flood warning networks across Australia.

About Doppler ultrasonics

The Doppler Effect (after C. J. Doppler 1803-53) is defined as, “the apparent change in

the frequency of sound or electromagnetic radiation due

to relative motion between the source and the observer,”

.)6891( scaasI & voravU(Dictionary of Science).

MACE Flo-series instruments utilise the Doppler Effect to measure velocity of stream flows. The MACE Flo-Series instruments transmit an ultrasonic (sound) wave into the flow. This sound wave is reflected by acoustically reflective particles (e.g. air bubbles, suspended solids) and the instrument detects the reflected frequencies. The difference between the transmitted frequency and the received frequencies is directly proportional to the velocity of the stream flow. In full or partially full pipes, the velocity of the stream flow varies markedly across the cross-section of the pipe. Typically, velocity is zero along the wall of the pipe and increases to a maximum at or about the centre of the pipe. MACE Flo-series instruments receive reflected frequencies from particles moving at these different velocities. The greater the area of flow moving at a particular velocity, the greater the number of reflections with the respective frequency shift. The average velocity of the stream is therefore calculated by averaging those frequency reflections received across the whole stream profile.

INTRODUCTION:

Many large open channels have been historically monitored

that has been “rated” using empirical data. Typically this rating is based on the depth of the water running over/through the structure. In recent times,

been negated somewhat by the advent of cheaper area/velocity methods, such as the MACE Doppler ultrasonic. However, thousands of rated structures are still used worldwide in diverse applications such as large open irrigation channels

wastewater treatment plants.

The MACE FloPro Series3 includes a powerful weir

enables the user to interface downward looking ultrasonic or submerged depth sensors, and convert the depth readings to

includes equations for all major

V-notch weirs (30°, 45°, 60°, 90°) Cipoletti weir

Rectangular weir

(contracted/suppressed)

THE PROBLEM:

Quail Mesa Ranch is a large irrigation ranch based near Ehrenberg, Arizona, USA. The irrigation water that is delivered to the ranch by the US Bureau of Reclamation (USBR) is distributed along a large concrete lined trapezoidal canal (approximately 35 ft (10.5m) in width). Water that is not used on-farm is diverted through a rated “slotted”broad-crested weir structure and returned through a pipe to a drainage ditch. This pipe has a very steep gradient and stream velocities often exceed 9 ft/s (3 m/s). The operators of Quail Mesa ranch, wanted to install an instrument at the broad-crested weir that could measure and record the

through the pipe to get a more accurate measurement than currently provided by the weir structure and it’s rating table.

CASE STUDY: FLUME AND WEIR MONITORING

Figure 1: The broad-crested weir structure at Quail Mesa Ranch, AZ.

THE MACE SOLUTION:

The priority of the operators at Quail Mesa Ranch was to measure and record the depth of the water going over the weir structure. With the ability to accept multiple sensor inputs, a MACE Series 3 FloPro was installed with a 4-20mA ultrasonic depth sensor (EchoSpan® by Flowline, CA). Although the

negated the use of this functionality.

Because of the highly expandable nature of the Series3 FloPro, highly accurate measurement of

Doppler ultrasonic velocity sensor is mounted in the pipe (partially-full) that carries water into the drainage ditch. In addition, because of the extremely fast velocities, an ultrasonic depth sensor will be mounted in the pipe to measure the depth of the cross-section.

An optional MACE FloSI – telemetry interface card will allow the data to be transmitted to a remote collection site in the future.

THE MACE FLOPRO BENEFITS:

1 Depth recording allows the Quail Mesa Ranch to analyze exactly when water was allowed to escape across the weir structure. These data can be used by the rancher to provide historical usage to the USBR.

2 Because of the highly expandable nature of the FloPro, up to three Doppler velocity sensors can be added in the future to allow highly accurate measurement of the tail-

drainage ditch.

3 With the MACE FloPro Series3, not only can

channels, critical information can be recorded from just about any environmental sensor.

4 With the optional telemetry interface, the FloPro Series3 can get all this information back to where the rancher needs it.

Figure 2: The Series3 MACE FloPro unit installed on Quail Mesa Ranch. An ultrasonic depth sensor (EchoSpan®) is mounted over the crest of the weir.

INTRODUCTION:

Metering surface water that is pumped from rivers or channels is a challenge that often fails traditional mechanical meters. The

trash-laden and moving at very high velocities (some in excess of 5 m/s (15ft/s)). The wear and tear on a mechanical meter under these conditions is immense, and consistently leads to failures and expensive repairs.

The MACE AgriFlo provides an extremely accurate and inexpensive solution for these types of applications. By using a MACE insertion velocity sensor, the MACE AgriFlo can be used in pipes from 100 mm (4”) to 2.5 m (100”) in diameter. Furthermore, with a Series3 AgriFlo, up to three pumps can be metered using one

innovation when more than a single pump is used at a pump station.

Because the MACE insertion velocity sensor provides very

and has no moving parts, the whole system is virtually maintenance free.

THE PROBLEM:

The Sacramento River in northern California, USA has a large number of river water extraction points that utilize electric powered pumps. Many of these pump stations have multiple pumps with pipe sizes generally in the range of 12 to 24“(300 to 600 mm) diameter. Historically these pumps

meters. However, with the high-trash content in the river, these propeller meters tended to break down regularly and thus require expensive servicing or replacement.

THE MACE SOLUTION:

The United States Bureau of Reclamation (USBR) installed twelve, Series3 MACE AgriFlo units on pump-stations along a stretch of the Sacramento River characterized by the pump stations having multiple pumps. In all locations the 2” insertion sensor was used for ease of installation and

solution to the monitoring problem.

THE MACE SOLUTION:

The California Department of Fish and Game installed a mix of 15 Series3 AgriFlo and FloPro units on various outlet pipes within the mosaic. Some 15 Series II AgriFlo’s were installed on inlet pipes in previous seasons.

Each AgriFlo/FloPro was equipped with a combined depth/velocity sensor mounted in the pipe using a MACE polypropylene mounting

with a FloSI card so that SDI-12 data could be transferred to a web-based telemetry device.

INTRODUCTION:

Lifting and conveying sewage through gravity sewerage systems and force mains requires monitoring to ensure that system capacities are not under or over-utilised. Moreover, the amount

from sewer treatment plants is a critical measure.The FloPro is an ideal instrument for use throughout the transfer and treatment systems of municipal departments. For use in lift stations, the MACE FloPro provides an extremely accurate and inexpensive solution. By using a MACE insertion velocity sensor, the MACE FloPro can be used in pipes from 100 mm (4”) to 2.5 m
