Can the LIQUI-VIEW be used in the vertical position?
The LIQUI-VIEW may be mounted in any position.
When positioning the instrument in vertical position make sure that the piping/tube is always completely filled with water.
When there is an shut off valve on the bottom make sure not to open the valve in one motion.
This causes an free fall and causes air to come in to the tube, this causes a wrong measurement, counter pressure is advisable.
