SCAD TM1 Tank Monitor with External Sensor Strip - 10040 Item # 880426
Description
The SCAD TM1 Tank Monitor with External Sensor Strip is an easy to install solution for monitoring the liquid level in one tank up to 30 inches tall by simply touching a pad. The system uses SCAD's external stick-on level sensors that cannot get fouled and the monitor automatically checks and alerts when liquid levels are critical and provides external alert power. The SCAD TM1 Tank Monitor has the same function, and is compatible with, the 10018 and 10024 sensors.
Features:
- Monitor water, grey water or holding tank level by simply tapping a touchpad
- External sensor easily sticks onto the outside of plastic and composite tanks and cannot foul (for water and waste
- Optional internal sensor available for metal tanks (sold separately)
- Compatible most fuel float sensors
- Small footprint: 2.2" x 2.2" x 0.3"
- Measures up to 9 increments (levels) of liquid
- Touch pad eliminates button failure
- Electronics are enclosed
- Can alarm on empty or full for water and waste tanks
- External alarm wire can power external device during alarm condition
- Compact surface mount size 1/2 inch hole required for wires
- Continuous read function provides hands-free monitoring while filling or emptying tanks
- Visual alarm that is user selectable on for empty or full
- Accommodates all tank shapes
- Easy to install, easy to operate, reliable and cost effective solution for monitoring tank levels
- Can be used with a variety of sensors
Specifications:
- Power: 12 / 24V DC
- Tank Monitor Dimensions: 2.2" x 2.2" x 0.3" (56 x 56 x 7.6 mm)

great meter, seems accurate.
Installation was straight forward. I found on some reviews to add a diode between the power supply wires to prevent motor start stop surges from damaging the meter. I put this in. The meter works great so far. I hope it lasts a long time.

Almost works
The problem is that it is not holding it's Empty and Full reference. I'll update my review if I can get a resolution. I'm an EE - I'm pretty darn sure I installed it correctly.

Five Stars!
I was very happy to find a monitor with external sensor. It was easy to install and wire, and it works perfectly.

SCAD calibration
Easy install, but calibration full and empty is confusing and a bit frustrating. Other than that it is a good monitor

Great solution for a holding tank
Put this on a new holding tank. Easy to install and good directions. Calibration requires understanding of the programming sequence. Works great!

Questions
How far apart and how close must the sensors be located on the tank?
The GAP between the inner edges of the sensor strips varies depending on the height of the strip. Also, the sensor strip should be made wider for short strip heights by overlapping additional sensor tape by 1/2 inch toward the outer edges. Below are the specs:
For a foil HEIGHT of 6-8", the WIDTH should be 3-3.5" and the GAP should be 1-1.5"
For a foil HEIGHT of 8-10", the WIDTH should be 3" and the GAP should be 1.5-1.75"
For a foil HEIGHT of10-12", the WIDTH should be 2" and the GAP should be 1.5"
For a foil HEIGHT of 12-14", the WIDTH should be 2" and the GAP should be 1.75"
For a foil HEIGHT of 14-20", the WIDTH should be 2" and the GAP should be 2"
For a foil HEIGHT of 20-24", the WIDTH should be 2" and the GAP should be 2.5"
For a foil HEIGHT over 24", the WIDTH should be 2" and the GAP should be 2.5-3"

Will this work on a fiberglass holding tank?
SCAD sensors can be used on fiberglass tanks, preferably no thicker than 1/2 inch. There are couple cautions. Some older boats had tanks made from fiberglass over a wooden core. It's not recommended to use SCAD external sensors in that application because the wood could absorb moisture causing inaccurate sensing of the tank level. A SCAD internal sensor can be used in the case of a wood core tank. Also note that some fiberglass tanks have a very rough exterior which could cause air gaps between the SCAD external sensor strips and the fiberglass. In this case, major voids that would cause air gaps should be sanded flat or filled with plastic such as resin or non-metallic body putty.

Can I use a 2 wire sensor on this device
The TM1 monitor will read two-wire resistance type sensors, both American 240-33 Ohm and European 10-180 Ohm types. If you're using the TM1 with a SCAD electronic external sensor, three wires are required from the monitor to the sensor.

How tall are the external sensor strips? My holding tank is 16” tall. Also, about the three wires from the sensor to the display, are there two sensor wires and one ground wire? If so, can I run a separate ground wire to the boats ground?
I looked at the new instructions and noted that there are only three wires from the sensor not four as I indicated. I would still just run all of these to the monitor harness.
