Question: How far can the meter be from the cistern?
Answer: There is no real limit for the length of the tube, but in the set only 30 feet is included. The practical limit lies around 150 feet. The tube is 1/4 inch pvc tubing that can be purchased at most hardware stores or fish-tank stores. The watertank can be higher or lower than the gauge, in the ground or on top of a roof
Question: Gauge says it reads up to 100". My cistern is 12 ft deep. Is this a problem?
Answer: The total scale of the gauge (that is a full 360 degree rotation) is 4 meters or approx. 13 feet. The numbers end at 100 inches but the scale runs further without a number indication (see attachment). Above 100 inches the depth can be estimated up to a maximum of approx. 13 feet, without damage to the gauge.
Question: How difficult is it to retrofit this gauge on an old (lift the concrete top and gaze in) cistern? The lid is getting heavier each year.....
Answer: The CisternGauge is especially designed for fast retrofitting. Easiest is normally to bring the sinker-weight in through the overflow. Installation can be as fast as in minutes. If there is no overflow reachable, then the 1/4 inch tube should be led into the cistern otherwise.
Question: Is the scale in inches?
Answer: The scale is in Inches, but a 1 meter and a 2 meter mark is also displayed in red numbers on the scale.
Question: If there is no electric, batteries and no vaccuum involved how does it work?
Answer: It works by applying pressure by squeezing the pressure bulb until the pressure equalizes the pressure at the bottom of the watertank. This maximum obtainable pressure provides a readout at the gauge, which is displayed in inches of fresh water.
Question: I use a plastic tank in my crawl space for cistern. Will your gauge work correctly in this environment?
Answer: The success of an application in a situation like this depends on the depth of your tank. This gauge is designed for a maximum
depth of somewhat over 6 feet. If your plastic tank has a depth of at least approx. 3 feet, the scale will still be useful.
Question: In a remote location, where we have no spare electrics, we need to see the level of a rainwater collection pit. This pit (below ground level) is pumped out every week by manually starting and stopping a sump pump. However, if the pump runs dry it gets damaged and this has happened several times. To make this an easier operation we need a simple visual level indicator. The pit is 1.65m pit and I thought your Gauge indicator may be the answer. I would appreciate your comments on this.
Answer: The meter gives you the depth of a water-reservoir (or well) in inches and meters up to approx. 2 meters of depth, so the scale is appropriate for your application as well. It is manually powered (pressure bulb) and contains no batteries or electrical components. The fact that you have a well, below ground level, makes no difference for the gauge.
Question: My cistern is 65 feet above my house. Can your gauge function correctly in my house, and, if so, how precise is it?
Answer: The cistern can be higher or lower than the gauge position. It does not affect the measurement at all. The precision is within a couple of inches. However, you will have to lead the gauge-tube from your house, first to the top of the cistern and then down into the cistern to the bottom. (Nót through a hole or pipe in the bottom of the cistern)
Question: My appartment is quite a distance from the overflow outlet. Can you ship one to me with 45 feet of tubing instead of 30 feet?
Answer: It is possible to order different lengths of tubing. (Please use "contact us").
Question: We have severe winters. Will the meter still work?
Answer: The system will work during winters too. But be careful, If there is an unbroken layer of ice on top of the water, the pressure cannot escape and therefore the read-out might be temporarily too high. The gauge itself will not be effected by frost, but it would be best to hang it indoors. The system is very easy to troubleshoot if it gets damaged and the system requires no batteries at all, which is generally good for winter-circumstances.There is no water but air in the tube, and therefore it can be led through cold areas without freezing.
