Abstract
The utility model discloses a distributed valve monitoring device, which consists of a sensor, a wireless monitoring node, a wireless relay point and a wireless monitoring terminal. The sensor measures working parameters of a valve, monitored information is uploaded to the monitoring terminal through the wireless monitoring node and the wireless relay point to monitor the working condition of the valve. When the pressure and flow of the valve are changed, the wireless monitoring terminal gives an alarm. The distributed valve monitoring device has the advantages that the distributed valve monitoring device is a distributed and flexibly operated valve monitoring system and is low in maintenance and installation cost.
Description
Technical field
The utility model relates generally to process industrial monitoring field, is specifically related to a kind of distributed valve monitoring device.
