THE LONG DISTANCE INDICATOR 



Where an indication of some distant water level is desired 

 and a record is unnecessary, the need is met by the No. 639 

 Long Distance Water Stage Indicator, operated by the No. 



Fi... .V.i. N,i. r,:;.i Imli.-itnr. 



Sender. A moving Pointer indicating on a dial 12 inches in 

 diameter, is operated by electro-magnets and a ratchet wheel, 

 in the same manner as the Long Distance Register. This dial 

 shows at any instant the height of the water at the distant gage 

 house. 



One or more of these Indicators may be put on the same 

 circuit with a Register. In many instances, it is desirable to 

 have an Indicator in the power plant for the information of 

 tin operator, while the Register is placed in the office of the 

 engineer, where the records are kept and studied.
