CX-OCFM-FM Wall-mounted open channel flow meter
Ultrasonicopen channel flow meteris a high accuracy flow instrument which is used the principle of ultrasonic measuring Venturi canal or Parshall flume.It measure the time of reflected back after sound wave contact to channel water , then according to the formula figure out channel flow, it can provide flow output, display flow velocity and total flow.

Warranty And Service
1. Warranty
The manufacturer provides one year warranty on all products, free of charge, but the users should be responsible for the one-way transportation fee from the customer to the factory.
2. Service
The manufacturer provides instrument installation for our customers, and the charges will be made according to the cost.
For any hardware failure of the instrument, we recommend that our customers send back the instrument to our factory for service, due to the fact that the instrument is made of microprocessors and it will be difficult to perform field maintenance. Before sending back the instrument, please try to contact the factory first to make sure what the problem is.
For other operational problems, please contact our service department by telephone, fax or email and internet. In most cases, the problem could be solved immediately.
