ADVANTAGES OF GURLEY CURRENT METERS 



Reliability in service. Gurley meters have been devel- 

 oped to meet the exacting requirements of field service. The 

 details of construction have been improved from time to ti un- 

 to insure continuous reliability under actual working conditions. 

 They may be depended upon to give accurate results under 

 trying conditions. 



Simplicity of design. The details of design are extremely 

 simple. The instrument is self-contained. There are no deli- 

 cate adjustments required, nor are there any exposed parts to 

 give trouble. 



Rigidity of construction. Gurley meters are strongly con- 

 structed. They will resist successfully all of the stresses and 

 shocks incident to travel and field service. 



Adaptability. Gurley meters are equally well adapted to 

 the measurement of small streams and large rivers. A single 

 meter may be used on both classes of work by simply altering 

 the method of suspension. 



Size. The compactness of the Gurley meter is a material 

 advantage. It can be packed, when traveling, in a box small 

 enough to be carried in a hand bag. Its size is also an advan- 

 tage in handling when in actual use.
