Applied in the flow detection, the value of the temperature difference in the performance area corresponds to the size of the flow. The working principle of the heat transfer temperature difference, in the closed probe placed inside the heat module and temperature sensing module, the probe's heat transfer temperature difference is closely related to the measured medium flow rate, when the medium in the pipeline to a stable flow rate of flow, the sensing module receives the heat module sensing is a fixed value. When the flow rate of flow through the probe changes, the heat-sensing module will transmit the temperature difference signal with the change, after the processor will correspond to the flow rate of the results output.
1. Without any moving parts, so compared with mechanical flow switches it will not fail due to corrosion, breakage, baffle deformation and other reasons;
2. Suitable for flow monitoring of different media, including some impure liquid and gas media;
3. Plug-in installation mode, to meet a variety of pipe diameter installation requirements.
4. Wide range of flow detection, high precision, to meet customer requirements for the control of different flow rates of fluids.
5. Digital display of the state of the media flow;
6. Key setting parameters, easy to operate.
7. Extra-long service life and maintenance-free design combined, so that your equipment to show a huge competitive advantage.
Pneumatic and hydraulic dual purpose, low flow rate alarm, can be used for pneumatic and hydraulic systems, can be used for circulating water, cutting fluid and lubricating oil cut-off detection, and pump idling protection.
For vertical installation, it should be installed on the pipe section flowing from bottom to top.
When mounted horizontally, the probe should be kept away from air and sediment.
