level indicator

level indicator

(OP)
Hi collegs,

Our company is building in Finland vacuumtankers to spread liquid manure on fields.
When the tanker is filled by the vacuum, the customers would like to know how much there is liquid manure in the tanker.
I have been looking for a low-cost electric or electonic device for the purpose. 12 volts DC is available.
Can anyboby help ?

RE: level indicator

Do you need to know only when full or actual level? If only full you could use a float tied to a switch. ISZ

RE: level indicator

Float switches are an economical option for tank level. Using multiple floats will enable you to identify discrete levels. Perhaps having 1/3, 2/3 and full.

Depending on size and shape of tank a sight level gage may work. Although you would have to evaluate the effectiveness of the glass with your intended liquid.

RE: level indicator

I am very familiar with the system that my Dad's 5,000 gallon liquid manuer tanker had. It had a 6" diameter float on the end of an arm that rotated on a shaft mounted perpendicular to the end wall of the tank. The level was simply read with an arrow attached to the shaft. You could do the same thing with a sealed bearing and put either an arrow or rotary sensor on the shaft. ISZ
