LEVEL ENABLE ALARM HYSTERESIS X XXX FT or meters 4210 Flow Meter Section 2 Programming The HYSTERESIS menu lets you set the range over which the level or other condition can vary before the flow meter responds to the change In the PROGRAM section of the software there are several steps that require a change in a condition to make the flow meter carry out certain actions For example step 6 programs the flow meter to enable activate a sampler In that step you select a condition or set of conditions that must occur before the sampler is enabled You enter a value level is an example that must be met before the enabling occurs But what if this value is met and then falls away It is possible for a condition to vary rapidly over a narrow range Without hys teresis the flow meter will turn the sampler off and on repeatedly causing a condition known as chattering that would result in very erratic operation of the sampler With hysteresis you can enter a value that will keep the flow meter from responding to insignificant changes in the enabling condition You should select a value for hysteresis that is narrow enough to allow the flow meter to respond to any serious change but broad enough to ignore minor changes that could cause chat tering Press Enter and the following will appear FLOW RATE ENABLE ALARM HYSTERESIS X XXX CFS or other units of measure The next several menus may or may not appear depe

Do not attempt this procedure unless you have the proper equipment available and know how to make electrical mea surements 4210 Flow Meter Section 1 Introduction To measure current for a varying load requires a more sophisti cated type of multimeter one that is capable of averaging high and low readings over a period of time The Fluke 87 Multi meter is one example of this type of meter You should set the meter on MIN MAX and let it run with your program for several hours or more Other manufacturers meters are also acceptable but only if they are capable of averaging current draw You should run the test for at least eight hours longer if necessary or until the flow meter has exercised the entire program The longer you run the test the more accurate the average will be Fluke 87 or other current averaging meter FLUKE 87 TRUE AMS MULTIMETER Flow Meter Connect Cable 60 1394 023 or you can make your own Battery 12 Volt 0000090 clip A good quality adjustable regulated DC power supply can be substituted for the 12 volt battery The power supply should have at least 3 Amperes output prefer ably more and capable of overcurrent surges Figure 1 3 Measuring Flow Meter Current More information about batteries used to power Isco equipment is available from the Isco Power Products Guide which is shipped with this manual and any flow meter o

This may lead the flow meter to detect the wrong wave and introduce a wave detect error Avoid Wind Currents As much as possible the ultrasonic level sensor should be installed in a location protected from air currents Wind reduces the strength of the ultrasonic pulse and echo This causes the flow meter to have difficulty detecting the proper wave in the echo resulting in a wave detect error In severe cases it is possible for the flow meter to lose the echo com pletely Avoid Excessive Distances Although the ultrasonic level sensor cannot be mounted closer than two feet from the maximum level of the flow stream it is recommended that the mounting be kept as close to the twelve inch limit as possible The reason is that the error made by the flow meter in calcu 3 15 4210 Flow Meter Section 3 Installation 3 16 lating the velocity of sound in the air is multiplied by the dis tance from the level sensor to the surface of the flow stream Minimizing the distance will minimize the error Calibrate at Expected Temperature The user should cali brate the level reading under temperature conditions as near as possible to those expected during operation For small changes of level the error due to temperature is determined by the product of the distance from the transducer to the flow stream surface and the temperature change Calibrating the flow meter at the same temperature as the expected operating temperature will minim

U shaped channels and pipe inverts 10 in diameter and less The term small flumes generally refers to 1 and 2 Parshall flumes It should be noted that the level measuring point for many types of flumes Palmer Bowlus Leopold Lagco etc is not in the flume but upstream in the invert of the pipe for these types of flumes the section of interest is in the pipe invert not in the flume itself Thus care should be exercised in the use of 10 or smaller Palmer Bowlus and Leopold Lagco flumes Determining Suitability The channel to be measured can be pre qualified by a simple equation to determine whether or not the channel is wide enough to allow correct positioning of the ultrasonic sensor Since the beam angle is 12 the equation is MinimumWidth 0 21 x Distance Where Distance is the distance from the bottom of the ultra sonic level sensor to the minimum expected level 4210 Flow Meter Section 3 Installation Distance Minimum Width q Figure 3 6 Foam and Oil on the Surface of the Stream Distance Minimum Width lt q Figure 3 7 Small Pipes and Narrow Channels 3 17 4210 Flow Meter Section 3 Installation 3 3 7 Associated Equipment 3 18 6 10 Alternative Flow Measurement Systems 3 7 1 Isco Sampler 3 7 2 Connection to Other Isco Equipment Because of the characteristics of ultrasonic liquid measurement there may be some installations where the ultrasonic met

H ions indicates alkalinity The H in pH stands for Hydrogen and the p stands for power The normal scale for pH runs from 0 to 14 with 0 being most acidic and 14 being most alkaline Distilled water at 25 C is neutral at 7 based on the fact that the dissociation constant number of H and OH hydroxyl ions present for pure water at that temperature is 107 The dissociation constant is a number indicating the degree of ionic dissociation for a substance after it is dissolved in water Dissociation constants vary widely for substances depending on the nature of the substance s chemical bonds Ionic salts tend to have higher constants Each number on the pH scale between 7 and 0 equals a tenfold increase in H ion Each number between 7 and 14 equals a tenfold decrease of Ht ion pH measurements of wastewater are commonly made to monitor the effect of treatment chemicals added to raise or lower the pH Water that has been used for various industrial processes may deviate substantially from 7 Chemicals are often added to the water to bring the pH close to that of neutral water which is 7 For example if the effluent has a concentration of heavy metal ions they must be removed before discharge Raising the pH of solutions containing transition metal ions will cause them to pre cipitate where they can easily be removed as sludge The resultant solution will be high in pH and will require acid to neu tralize it Figure 4 8

The defaults are all zero You must have the appropriate sensors attached to the flow meter to measure temperature D O pH conductivity etc the flow meter cannot do this by itself nor does it occur automati cally SAMPLER ENABLE means that in a combination flow meter sampler pair the flow meter controls the sampler s ability to run its own program The difference between step 5 sampler pacing and step 6 sampler enable is that in sampler pacing the flow meter merely sends flow pulses to the sampler from time to time The sampler counts these flow pulses to determine when to take a sample according to its own programming With sampler pacing the sampler is always enabled With sampler enabling the flow meter can actually stop operation of the sampler The sampler is still set up to run its own program but the inhibit enable line from the flow meter will determine when and whether the sampler runs its program This feature is useful for storm water runoff monitoring applications where it may be necessary for the flow meter sampler pair to have to wait a long time between storm intervals Again changing or meeting a condition or set of conditions triggers the enabling The conditions that can be used for sampler enabling are similar to those used for sampler pacing level flow rate rainfall temperature dissolved oxygen pH or a combination of these conditions The YSI 600 Sonde provides several measurements at the same t
