Continuous Pressure Meter for Pump Sta. 1

[jfield001]

Hi all,

Here is my dilemma. A pumping station was designed for pumping against a pressure of about 14 psi. Recent events have shown that the current pumps in the system are ineffective at times as the station over flows with "crap". In order to redesign the station for the appropriate pumps, we need to know the actual pressure we are pumping against. So here is my question, where can I find a constant monitor/recording pressure meter that can store data including the peak pressure and duration? The line is a 4" ductile and we can tap a check valve that is 0.25” port that exists to get pressure in the line iron pipe. The pressure range I am attempting to monitor is between 0-100 psi. Also will be hoping to collect data for 3-4 weeks.

The field engineer seems to think there is a particular event causes the pressure to spike to around 50 psi (meaning there are other pumping stations that fail in the area).

Any jargon or technical device name that can point me in the right direction would be greatly appreciated.

Thanks!

The Telog 31i recorders measure water pressure at user programmable rates up to 20 samples per second. The HPR-31i is compact, battery-powered and easy to use.

A single channel data logger that stores 32,512 sample points that is set to a sample rate of one minute will run for 22.5 days before the memory is full.

Those are just what I was looking for, thank you, bimr!
