Excellent Low Flow Capabilities.
Using sapphire bearings and design elements to reduce friction the Hays IP-81 Insertion Meter gives excellent low flow monitoring.
Installs In A Wide Range of Pipe Sizes.
A depth adjustment system allows the probe to be set for installation in a range of pipe sizes from 1/2" to 2". This preset depth insures error - free installation for optimal results.
Signal Can Interface Without Signal Conditioning.
Square wave signal can interface with many programmable controllers and computer cards without signal conditioning.
Signal Sent Through Unshielded Cable Hundreds of Feet.
Solid State Hall Effect Sensor is used to detect passage of six rotor blades. This eliminates magnetic drag and produces a square wave signal which can be sent up to 2000 feet over unshielded cable without a transmitter.
Field Repairable.
If damaged by dropping or other impact, the bearings and rotor can be purchased separately or a rebuilt IP kit containing rotor, bearings and replacement O-rings. This replacement is both simple and easy with a small screw driver.
