  • Delivery of chemicals
    Patent number: 11644019
    Abstract: A chemical delivery system connects to a chemical tank and includes a union connected to the tank outlet and providing an antirotation feature, in addition to threads, to prevent rotation of the assembly in response to asymmetric loads. A measuring tube alternately receives liquid from the tank and is isolated from the tank. While isolated from the tank, liquid is withdrawn from the tube by a pump under conditions allowing the pump to be calibrated. The assembly is cantilevered from the tank outlet and is of reduced length and weight producing a device which is not prone to overstress the tank outlet.
