Yes, we can agree with the given statement.
A measurement will be reliable, meaning that the person taking the measurement will get the same data of measurement no matter when or where he takes it. But that doesn't mean that it is valid or measuring correctly what it is supposed to measure. A measurement can be reliable without being valid. However, a measurement cannot be valid unless it is reliable.
If a length measuring scale is reliable, it measures the same length every time if we measure an object's length unless the object is not changed. However, if the scale is not proper, this number may not be the actual length. In such a case, it is an example of a scale that is reliable, or consistent, but not valid. For the scale to be valid and reliable, not only does it need to measure the same length every time we use the scale for same object, but it also has to measure the actual length.
