M-25 Method of Operation

The sensors operate on the principle of single gap light absorption as a means of detecting the presence of suspended solids. The sensors utilize a near infrared emitter to minimize color effects and compensates for emitter variations due to temperature by measuring source brightness.


Suspended Solids Sensor

Continuous Wireless System



20 Series Wireless

The Insite Instrumentation Group Model 25 (M-25) suspended solids sensor is a unique product that combines advanced electronics with solid-state, optical sensing technology. The sensor is based on the field proven design of the Model 15 family of sensors with almost 3,000 units shipped. To this proven design, the Model 25 adds the ability to mount the sensors throughout the plant without having to deal with running conduit between the sensor and analyzer. This allows for significant savings on installation costs while also allowing maximum flexibility in sensor placement. No other suspended solids sensor can compare with the features and benefits of this revolutionary design.

Sensor Transmitter | ST 2

The M-25 sensor connects to a Sensor Transmitter (ST 2) junction box. The ST 2 then communicates with the Process Transmitter (PT 2) via a ZigBee compliant Rf module. There is an embedded antenna which provides an outdoor line of sight range up to one mile. When several ST 2 / Sensor pairs are installed they form a self-healing mesh network that increases reliability.




Model 25 Suspended Solids Probe (M-25)

M-25 SS Probe

The M-25 Sensor is our standard suspended solids sensor configuration. This includes the 1-1/2" NPT male mounting thread, 1/4" quick connect tube fitting for the integrated jet clean, and 33ft (10m) of sensor communications cable. Additional cable length is available upon request.

Recommended for: 250 - 30,000 mg/l



Model 25L Suspended Solids Probe (M-25L)

M-25L SS Probe

The Model 25L Sensor is designed to measure very low solids concentrations typically found in secondary clarifier and plant effluents. This model has a PVC 1-" NPT male mounting thread.

Recommended for: 0 - 1500 mg/l



Model 25PI Suspended Solids Probe (M-25PI)

M-25PI SS Probe

The M-25PI Sensor is intended for inline monitoring in a large diameter pipe. The mount is 2" NPT male thread in 316 stainless steel that works with a customer supplied 2" Thread-O-Let. The integrated jet clean with this sensor includes an inline check valve. There is a flow indication groove on the back of the sensor mount that should be parallel with the flow. Maximum in-line pressure is 20 psi. See the 20 Series System Manual manual for additional information.

Recommended for: 250 - 30,000 mg/l


Model 25T Suspended Solids Probe (M-25T)

M-25T SS Probe

The M-25T Sensor is intended for inline suspended solids monitoring utilizing a by-pass loop. The by-pass loop is generally configured using customer supplied full port ball valves on both sides of the tee. The supplied tee (as shown) is 3" schedule 80 PVC, with slip connections for process piping and a 2" female NPT connection for the SS probe. The integrated jet clean with this sensor includes an inline check valve. There is a flow indication groove on the back of the sensor mount that should be parallel with the flow. Maximum in-line pressure is 20 psi. See the 20 Series System Manual manual for additional information.

Recommended for: 250 - 30,000 mg/l



Model 25HT Suspended Solids Probe (M-25HT)

M-25HT SS Probe

The M-25HT Sensor combines the ease of use of a hot tap mount with the reliability of the InsiteIG SS Sensor. The mount is a 2" NPT male thread in 316 stainless steel that works with a customer supplied 2" Thread-O-Let, saddle or existing piping. The integrated jet clean includes an inline check valve. There is a flow indicator on the back of the sensor mount that should be parallel with the flow. Maximum in-line pressure is 40 psi.

Recommended for: 250 - 30,000 mg/l
