Water measuring system with improved calibration
First Claim
1. A water measurement apparatus for measuring different parameters of water comprising:
- a housing;
a plurality of individual sensors mounted on the housing, including an oxygen measuring sensor, the oxygen measuring sensor being mounted at a position separate from the other sensors, andmeans for enabling a calibration of the sensors other than the oxygen measuring sensor, including a container for providing a liquid at a position that will only contact the sensors other than the oxygen measuring sensor, wherein the container is configured to extend around the oxygen measuring sensor.

Abstract
A water measuring system for measuring different parameters of water having a compact configuration that can be easily calibrated is provided. A plurality of individual sensors, are mounted on the housing, including a dissolved oxygen measuring sensor that can be mounted at a position separate from the other sensors. A hood member can be mounted at the lower end of the housing member to protect the sensors. A container that is capable of holding a calibration liquid can be fitted onto the housing member to provide the liquid at a position that will only contact those sensors other than the oxygen measuring sensor during a single calibration procedure.

10. In a water measurement system for measuring several parameters of water with a plurality of individual sensors mounted on a common housing, the improvement comprising:
-
a housing member mounting a plurality of individual sensors at a lower portion of the housing; an oxygen measuring sensor mounted on the housing member at a position above each of the other sensors; a calibrating liquid capable of calibrating the individual sensors mounted below the oxygen sensor, and a container configured to interface with the housing member and holding the calibrating liquid in such a manner as to extend operatively about the individual sensors except for the oxygen sensor. - View Dependent Claims (11, 12, 13, 14, 15)

16. In a water measurement system for measuring several parameters of water with a plurality of individual sensors mounted on a common housing, the improvement comprising:
-
a housing member mounting a plurality of individual sensors at a lower portion of the housing; an oxygen measuring sensor mounted on the housing member at a position above each of the other sensors; a hood member removably mounted to the housing member and extending downward from the housing member to encompass each of the individual sensors, and a container configured to interface with the housing member and to extend within the hood member, the container is further configured to hold liquid within its central portion and to have a perimeter enveloping wall which excludes the oxygen measuring sensor, whereby, when a calibrating liquid is inserted within the container, it can operatively contact each of the individual sensors with the exception of the oxygen measuring sensor. - View Dependent Claims (17, 18, 19)
