JC703 Coax Guided Wave Level Transmitter
Guided wave radar level meter are a kind of measuring instrument based on the time travel , radar wave are travelling as light speed , the travel time can be transformed into level signal by the electronic parts . The detector can send the HF pulse and spread along cable , when the pulse meet the level surface , it will be reflected and received by the receptor inside the instruments , then the receptor will transform the distance signal into level signal. This model is for liquid with small dielectric constant.
Features
1) For liquid with relatively lower electric constant , we can use the transmitter with twin rod probes to get good and precise measurement .
It is suitable for measurement of any liquid with dielectric constant no less than 1.6
2) Viscosity of the liquid should be no more than 500cst
3) Maximum measuring range of the transmitter with rod probe is 6 meters .
The measurement cannot be influenced with steam and foams .
