Product Information

Comprehensive technical details and specifications for our industrial tank gauging solution

Product Description

Without adequate pressure upstream of the LLD, the unit will reset into the slow flow position every time the pump turns off. This does not mean that the LLD must have a functioning check valve in the STP head. Pressure must simply be maintained upstream of the LLD.
