Telog - Model IFM-32 -Insertion Flowmeter

The Telog IFM-32 provides benefits in the following areas:

1. Non-Revenue-Water, where it is used for District Metering and Minimum Night Flow (MNF) analysis to identify and prioritise zones in the network for leak detection and rehabilitation.

2. Situational Awareness, where real time flow data and associated alarms provide utility operations teams with insight into current and developing situations in the network enabling rapid and in some cases pre-emptive responses.

3. Operational Efficiency, where deeper insight into flows in the distribution network allows better calibrated models and enables better planning and decision making.

4. Billing, where it may be used as a backup to existing meters or at locations where deployment of a Mag meter is not commercially viable.

The IFM-32 is an insertion flowmeter, enabling retrofit in existing networks without service interruption and available in various lengths for permanent or portable applications. As it is battery operated, the Telog IFM-32 can be quickly and cost effectively installed at a variety of locations in the network, providing insight into flows that would not be otherwise cost effective. Combined with a Telog Ru-32A series RTU, the Telog IFM-32 enables monitoring of flows, pressures, pumps, valves and pressure transients in a single battery operated solution. All data captured is available for visualization, reporting and analysis in Trimble Unity Remote Monitoring, Telog Enterprise and Telogers for Windows application software for all water analysis applications.

The Telog IFM-32 can be used throughout the water distribution network:

• District and Zonal Metering

• Pressure Reducing Valves

• Pumping stations, water pipes

• Night flow monitoring and meter testing

The Telog IFM-32 insertion flowmeter consists of:

The electromagnetic sensor
The sensor contains the electromagnetic coil and stainless steel electrodes. All materials in contact with the water are approved and certified for use in drinking water. The sensor assembly is securely fixed to the stem, but can be replaced should damage occur during installation or handling.

Integral processing electronics (transmitter)
All flow processing electronics are contained within the IP68 housing fixed to the top of the stem. The IFM-32 has a wide, bi-directional measurement range from 0.066 ft/s to 16.40 ft/s (2 cm/s to 5 m/s) and its accuracy of ± 0.0066 ft/s (±2 mm/s) at flows up to 0.33 ft/s (10 cm/s) enables precise Minimum Night Flow monitoring (MNF).

Gland assembly and stem
Every unit comes with gland assembly, pressure measurement port, reinforced stem with an anti-ejection chain, locking nut and insertion point clamp to ensure correct and safe installation in pressurised water networks. Communication and optional external power input is via a single watertight military specification connector.
