SMITH8013C Smith Loading  control apparatus is the control instrument supporting with Smith flowmeter, it can use as a general flow  calculate instrument and also can work in pressure, temperature transmitter to measure testing medium pressure , temperature  real-time,and use high precision  mathematic model to achieve automatic compensation and product flow; Batch control, top and bottom limit control etc.

 characteristics
1. Can show the accumulation of tested medium flow, instantaneous flow, instantaneous pressure and temperature instantaneous.
2. 8 preset number can be set and can the on-line modification.
3. be instantaneous flow pressure, temperature, instantaneous instantaneous the limit alarm and control.
4. upper setting for flow and pressure, temperature and other parameters .
5. for flow batch  control continuous or interrupted
6. After Compensation instantaneous flow ，signal output  4-20 mADC  for recorder or PC use,
7. automatic test a meter output frequency. Has the power function of data protection;
