PipeAlarm2 LTE/UMS
battery-operated and LTE based district heating pipeline monitoring device
The PipeAlarm2 LTE/UMS equipment series by LANCIER Monitoring is the compact, battery-operated monitoring solution for pipe networks with a pair of monitoring conductors in the insulating layer. It is easy to install and easy to operate. On-site power and network connections are not required. Alarms are sent via LTE or GSM networks.
PipeAlarm2 LTE/UMS provides for a 2-channel parallel monitoring of the flow and return in a district heating pipeline. Therefore the equipment measures the insulation and loop resistance of a pair of conductors in the insulating layer of the pipe (Cu System (Nordic), Hierarchical Systems (HDW, JR Isotronic) and NiCr System) in accordance with EN 14419.
Additionally, there are two access ports for dry contacts, to monitor external signals (e.g. float switches). Where there are leaks in the pipe, a break in the measuring loop or in the pipeline joints and where there are changes in the state at the contact ports, these raise the alarm and thus help to prevent greater damage and losses.
PipeAlarm2 LTE/UMS equipment takes measurements at least daily (more frequently can be configured at will, near contacts are polled at 10-second intervals) and sends a message to the UMS server via mobile data connection if there is an alarm.
A weekly status message is always sent, which reports the condition of the equipment.
The last 90 measurements are stored securely in the internal EEPROM memory.
Configuration, setting the limit values for the loop and the insulation resistance, as well as reading off the measurements can be carried out on-site on a laptop via the USB 2.0 port.
