Claims

[Scope of utility model registration request]

A transparent SV measurement tube that accommodates a predetermined volume of collected sludge liquid to be measured via a valve connected to the bottom, an optical SV detection section disposed along this S measurement tube, and this SV detection section. SV that converts the detection signal from S to a measured value and outputs it.
a measurement conversion circuit, an air pump connected via piping and a valve from the top of the SV measuring tube to depressurize or pressurize the inside of the SV measuring tube by switching the valve, and an air pump connected to the piping to open the inside of the front Bv measuring tube to the atmosphere. A sludge volume measuring section equipped with an atmosphere release valve is installed with its SV measuring tube positioned below the sludge liquid level of the sludge liquid tank to be measured, and one end thereof is opened into the liquid of the sludge liquid tank to be measured. A sampling pipe that is installed and connected to the bottom of the SV measurement pipe via a valve whose other end is installed at a lower position than the SV measurement pipe, and the valve connected to this sampling pipe. A sampling system comprising: a discharge pipe connected via a discharge valve to a branch pipe branched in front of the connecting end of the sampling pipe; and a discharge pipe for discharging the sludge liquid to be measured in the SV measurement pipe via the valve of the SV measurement pipe. A sludge volume measuring device characterized by being equipped with a piping system.
