We have a number of Aquatape Metritape sensors that we used at sites with CR10X loggers, I am changing out the CR 10X for a CR 1000 and have run into a problem when I write the program . I started out using Short Cut to add in my sensors, battery voltage, etc.
Short Cut has a similar sensor I can add in but it has three wires (signal in, signal out, and ground) , my Metritapes only have two wires.
How should I program this in CR Basic?
Here is an example from a CR10X program
Wiring diagram
Upstream metritape (White) Vin=SE1 (black) Vout=G There is a 10k resistor between E1 & SE1
Code for Edlog
9: Excite-Delay (SE) (P4)
1: 1 Reps
2: 24 250 mV 60 Hz Rejection Range (Delay must be zero)
3: 1 SE Channel
4: 1 Excite all reps w/Exchan 1
5: 100 Delay (0.01 sec units)
6: 250 mV Excitation
7: 6 Loc [ Res_Mt_up ]
8: .004 Mult
9: 0 Offset
10: BR Transform Rf[X/(1-X)] (P59)
1: 2 Reps
2: 6 Loc [ Res_Mt_up ]
3: 10000 Multiplier (Rf)
11: Z=F x 10^n (P30)
1: 307.60 F ;Resistance found on Metri_tape Tag
2: 0 n, Exponent of 10
3: 8 Z Loc [ Ohms_FtUp ]
12: Z=F x 10^n (P30)
1: 28.48 F ;Offset calculated from staff gauge reading to make true
2: 00 n, Exponent of 10
3: 9 Z Loc [ Offset_up ]
13: Z=X/Y (P38)
1: 6 X Loc [ Res_Mt_up ]
2: 8 Y Loc [ Ohms_FtUp ]
3: 10 Z Loc [ Raw_stgUp ]
14: Z=X-Y (P35)
1: 9 X Loc [ Offset_up ]
2: 10 Y Loc [ Raw_stgUp ]
3: 11 Z Loc [ Stage_UP ]
Thanks in advance for any help.
Never mind I got it working with a half bridge command.
Tim this is very late, however in an effort to document options for the Metritape (AquaTape) sensor I am adding this post update.
ShortCut still includes a Metritape sensor file 'AGS Level Sensor ((Metritape)' in most dataloggers - at this time the only dataloggers that don't include the AGS Level file are the CR1000X, CR300Series, and CR6. If you need to add the Metritape sensor you can add it by creating a program for one of the others and then either make adjustments for the new dataloggers or call Tech Support.
The Metritape sensor is now sold by JOWA
Hi,
would not it be easier to convert the DLD into CR1 with LoggerNet transform?
