The HWM Multilog 2 is a versatile multi-channel data logger with multiple analogue, digital, and serial inputs, it allows simultaneous monitoring of flow, pressure, and leakage, giving operators a complete picture of network conditions to spot inefficiencies and leaks early. Its GSM/GPRS communications provide reliable remote data transfer, ensuring field data is always available for faster, more accurate decision-making.
The IP68-rated housing ensures long-term durability in submerged or harsh environments, while its long-life battery reduces site visits and maintenance effort — delivering lower operational costs and greater uptime.
By combining robust connectivity, flexible sensor support, and a rugged design, the Multilog 2 empowers water utilities to improve efficiency, prevent costly failures, and deliver a more reliable water supply.
Applications of HWM Multilog 2
Key Features:
TECHNICAL SPECIFICATIONS
|
Features |
Specifications |
|
Input Options |
|
|
Digital |
HWM SonicSens 3 ultrasonic level sensor and Leak Noise Sensor (LNS). Third party sensors using Modbus or SDI12 communication protocol. |
|
Analogue |
Internal pressure transducer. 0-20 bar / 0-200 meters head / 0-300psig, 0.1% repeatability / please note that the logger is calibrated to 10 bar as standard. (20 bar calibration must be specified at time of order if required) External pressure transducer (contact for more details), Voltage (0-1V or 0-10V), Passive or active 4-20mA Temperature |
|
Serial Input |
Uni- or bi-directional pulse Up to 64 pulses per second |
|
Communications |
|
|
Local |
Hi-speed USB for connection to hand held devices, Windows tablets, laptop or desktop PC |
|
Internal Cellular Modem |
Cellular modem supporting 2G/3G/NB-IoT/LTE-M (Cat-M1) with SMS backup where available - (contact for available options). 2G/3G/4G NB-IoT can send data down to every 15 mins, with appropriate battery pack |
|
Accelerated dial-in |
Dial-in rate is increased if alarm situation is triggered. Logger can accelerate dial-in at alarm level for multiple applications - including SonicSens 3, Flow, Pressure and other alarmed sensors. |
|
Features |
|
|
Frequency |
Variable logger sample rate from 1s to 24hrs (this may affect battery life and communication costs) |
|
Logger/Site ID |
7 alphanumeric characters. Readable factory set serial number in firmware |
|
Dimensions (HXWXD) |
257x129x77mm |
|
Construction |
Die-cast aluminium enclosure, powder-coat spray painted |
|
Weight |
1.6kg |
|
Operating temp. |
-20 to +60 C |
|
Ingress Protection |
IP68 submersible |
|
Power |
Typical 5 years (depending on settings and signal condition). External power connection for battery box and third-party devices |
|
Memory |
Standard recording: 2 million readings (optional up to 64 million readings and expandable HC SD card) |
|
Fast Logging (secondary channel) |
Secondary, fast channel supports sampling up to 25 Hz and record average. minimum, maximum, standard deviation or time interval between pulses (for data smoothing) |
|
Pulse Interval Timing |
Count and Event logging modes independent for both recordings. Pulse Interval Timing helps to smooth readings (e.g. leakage) in low flows by counting the time between each pulse (event mode). This is available in addition to totalling the pulses (count mode) |
|
Alarms |
Multiple alarm options including Rate of Change, Profile, Minimum Night Flow and Threshold. 16 alarms per logger. Can be programmed to auto dial up to 8 telephone numbers on alarm. Over 16 alarms per logger depending on channel configuration |
